Golden Artist Colors produces a large assortment of products that impart shimmering iridescent or interference reflective qualities. This Information Sheet discusses what these paints are and how the artist can incorporate them into an artwork

Interference Colors Iridescent Colors Metals & Natural Colors
GOLDEN produces 6 Interference Colors in Coarse and Fine sizes. The fine particles produce a more even sheen, while the coarse particles add more sparkle, especially on uneven surfaces. GOLDEN Iridescents are offered in a variety of colors. Some of the 8 colors are offered in the coarse size, without appearing ” glitter-like.” These reflective pigments are either actual metals, synthetic lamellar iron oxides or naturally produced mica flakes that are mined from the earth.

PRODUCT DESCRIPTION

The GOLDEN Iridescent and Interference Colors achieve their reflective properties by synthetically reproducing several natural phenomena-the nacreous, or pearlescent, qualities found in fish scales or the dust of a butterfly”s wing, and the shiny and reflective qualities found in certain metals and minerals.

“Coarse” Iridescent and Interference Colors are simply larger particle size versions of our “Fine” Iridescent and Interference products. Coarse colors in the Iridescent line include Copper, Copper Light, Gold and Pearl. The Coarse Interference Colors are Blue, Gold, Green and Red.

All of GOLDEN”s Iridescent Colors produce a luster quality by themselves, or when mixed with other colors and mediums. The GOLDEN line of Iridescents can be separated into 3 groups based on chemical composition.

Group I: These colors are derived from mica platelets. They are then coated with an extremely thin layer of titanium dioxide. Refraction and reflection of light at the titanium dioxide layers produces various colors and pearlescent effects. Group I pigments include:

  • Interference Colors
  • Iridescent Pearl (Coarse and Fine)
  • Silver

Group II: These colors are also derived from mica platelets, but an iron oxide coating causes Group II pigments to possess hues in addition to pearlescent qualities. This group includes:

  • Iridescent Gold (Coarse and Fine)
  • Iridescent Copper and Copper Light (Coarse and Fine)
  • Iridescent Bronze

Group III: A third group consists of reflective colorants that do not fit the above descriptions, including highly metallic pigments:

  • Stainless Steel (Coarse & Fine)
  • Micaceous Iron Oxide
  • Mica Flakes (all varieties)

Luster Arises from Layers of Pigments:

The pigments in the first two groups (non-metallics) are composed of very thin, highly reflective and transparent platelets. Although the pigments themselves are transparent, the optical illusion of color is produced by the multiple reflection of light between microscopic layers.

The Phenomenon of Light Interference:

The property at work in the Interference Colors is known as light interference, most commonly seen in the rainbow effect created by a thin layer of oil on the surface of water. Thomas Young identified this phenomenon in 1801 in a series of investigations that were eventually instrumental in advancing the theory for the wave-like nature of light. Whenever light strikes a boundary between two materials of different densities, the light will either be reflected or refracted. If the refracted light encounters yet another boundary between materials of different densities, this light will again either be reflected or refracted. This process continues every time a new phase is encountered.

Light interference results from these concurrent multiple reflections and refractions of light. If the interference is constructive in nature, a strong color stimulus results. With Interference colors, a specific thickness of the titanium dioxide (TiO2) layer allows only a narrow spectrum of color to be reflected in phase, while all other reflected colors undergo destructive interference and are not observed. Since these pigments are transparent, a portion of the light will be transmitted and the resulting color will appear as the compliment to the reflected color.

Excellent Weathering Resistance:

Mica is quite insoluble in strong acids or bases, is inherently lightfast, and remains unaffected by water. When combined with a 100% acrylic medium, mica yields very stable paints that offer excellent permanency.

Mica”s chemical and UV resistance properties distinguish the Iridescent Mediums from most metal pigments, such as coppers, bronzes and even aluminum flakes. Metals have a tendency to rust or corrode as they continually oxidize over time. With the Iridescent colors, all components are already in the most stable state of oxidation, and there is no possibility for change resulting from further oxidizing reactions.

The metals that GOLDEN has chosen to offer are known to demonstrate remarkable durability. GOLDEN Stainless Steel (Coarse & Fine), which consists of extremely durable 316L grade stainless, is very resistant to salt spray and acid spotting, as well as alkaline cleaners or detergents. The Micaceous Iron Oxide, although highly reflective, is not in a metallic state but is already oxidized.


PRODUCT APPLICATION

Maintaining Bright Surfaces: The Options.

The highly reflective flake pigments used to produce Iridescent Mediums are extremely thin. These platelet pigments range from 1 to 2 microns in thickness, and up to 90 microns in diameter for the Fine and 180 microns for the Coarse. Consider that the surface of an average flake of Iridescent Pearl could carry over 50,000 Carbon Black pigment particles placed side by side. Due to the larger particle size and the transparent nature of mica, iridescent colors tend to be less potent than other acrylic formulations.

Although no rule is absolute, some procedures for maintaining bright surfaces have proven their effectiveness. What follows is a brief review of some of the more successful approaches.

  • To produce the brightest colors with the Interference line, add a very small amount of black-1:100 or less. The black will strengthen the reflected color. Add more black if darker colors are required.
  • To maintain the brightest possible effects with Iridescent Colors, avoid mixing them with opaque colors.
  • Be aware that blends made with matte materials such as matte mediums and matte gels will also reduce iridescent qualities by scattering the light that hits the surface. Adding gloss materials, such as GOLDEN Gloss Gel, increases interference qualities by heightening reflectivity. The addition of Gloss Gels and Mediums also provides better spacing between pigment particles, maximizing the effectiveness of each reflective pigment.
  • Overall, thicker applications will cloud the paint and weaken the intensity of the Interference Colors. Thinner applications increase the interference qualities. As the level of dilution increases, the pasty look disappears. Applying thin layers, whether by wash or glaze, effectively forces particles to lay flat with the large broad side facing the viewer. As more particle surfaces are exposed, the shimmer or luster increases.

Other Techniques and Considerations:

Since the Iridescent and Interference colors are relatively transparent, it is important to consider the impact of the base coat. By varying the color of the base coat, the overall color effect can be varied dramatically, especially when the Iridescent or Interference layer is applied transparently. For example, Interference Blue can be applied in glaze form over a light yellow or a dark red to yield some unique effects. Relatively transparent colors can be wet-blended into the Iridescent or Interference colors to produce other interesting results. Combining additional colors and Gloss Gels and Mediums can create some exciting glazes, in thin or thick films.

The important thing to remember about the Iridescent and Interference Colors is not to take them at face value. They can provide a range of colors and effects never before available, and many of their uses have yet to be discovered.

Painting Tips and Techniques

Painting Tips and Techniques

Paint is a compound that does more than bring color to almost anything— it’s a substance that allows us to grow and expand our creativity. From discovering new ways of using color to painting the perfect stroke, at Horizon Group USA, we believe everyone can learn through creativity. So, whether you’re an aspiring painter or an experienced one, we’re sharing our favorite techniques so you can keep adding color to your world!

Dress the Part

Some paints can leave permanent stains on furniture and clothing! Be sure to wear a smock, apron, or other attire you wouldn’t mind adding a little extra color to — and protect your work area with newspapers or paper towels, even if you’re using an easel.

Find Your Paint!

From watercolors to acrylics, finger-paints, and washable tempera paints, picking paint for your project depends on the artistic style you’re going for.

Use watercolors to create fluid and flowy designs. This type of paint is great for creating landscapes, skies, or even tie-dye designs because it’s not just your paintbrush that guides the color — but the water, too!

Acrylic paint is fast drying, which allows you to add multiple layers onto a painting — and even paint over any mistakes! It’s easy to create super vibrant colors and textures using acrylic paint — and, with a little bit of water, you can even make it look like watercolor! The one potential downside? Acrylic paint is permanent and will leave stains on anything it touches — clothing and furniture alike. So, remember to cover up anything you don’t want to get paint on while using acrylic!

Just like acrylic paint, tempera paint is great for layering and easy to create vibrant colors and textures with. Unlike acrylic paint, tempera paint is washable — meaning it won’t leave permanent stains on clothing or furniture. Although it does take longer to dry than acrylic paint, tempera paint is perfect for those who love to create outside the box — or the canvas!

Pick a Brush, Any Brush!

But which is the right brush for your masterpiece? The truth is, probably all of them! Use thick, wide brushes — called wash brushes — for covering large parts of a canvas or surface quickly and easily.

Brushes with slanted tips are perfect for creating lines and shapes that vary in thickness and coverage. Rounded brushes feel like you’re holding a pen or a pencil, and they’re perfect for adding details with maximum control.

Thin tipped brushes are perfect for little details and are great for adding words and phrases to your masterpiece. No matter the brush you use, just make sure to paint your strokes in the same direction — adding extra layers as needed for maximum coverage.

Plan it Out

A blank slate can be intimidating at first. Before you put brush to canvas or figurine, plan out your design. Refer to packaging for inspiration, and get to know your colors by testing them out on a piece of paper first! If you’re working with a canvas, use a pencil to draw out your design. Freehand is freeing, but laying the groundwork can help you produce your best work.

Create Your Own Color Palette

ROY G BIV. Most of us have heard of the acronym, but some of us may not have experimented with our rainbow: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Working with this standard family of colors gives us the chance to make each one completely unique — and mixing them together can help you add some fun dimension to your painting. Whether it’s creating all-new colors or varying shades, use a paintbrush and a palette to mix and blend standard colors together to create a color scheme that’s uniquely your own. Use white to create a lighter version of the same color and black to create different shades! Or, follow the color chart below to create different colors of paint — even if you don’t have them in a tube:

Lots ‘o Layers

Layering paint really is as easy as it sounds — just apply one layer after another, working from the bottom up. Start with big swipes of color, then refine as you continue painting. Whether you’d like to make a single color more vibrant or create an ombré effect — mastering the art of layering paint is the key to creating a masterpiece.

Creating Texture

When it comes to adding texture to any painting, the opportunities are endless! Add a mass of dots to create a bumpy look and feel to your painting, while adding depth — a technique called pointillism. Try crumpling up a piece of paper, dipping the ends into your paint, and gently dabbing onto your surface. Or, see what happens when you use sponge dabbers! Maybe you’d like to go even bolder with your textures by introducing another component, like fuzzy sticks or feathers. Whatever you choose, just remember to let your imagination guide you — and feel free to have fun!

Splatter Painting

Who says you can only paint with a paintbrush?! Put some paint on your paintbrush, dip it into a water cup, then flick or splatter your paint onto your canvas or work surface to create an abstract landscape, stellar stars, or just some fun texture!

Experiment with Mediums!

The beauty of painting is that you can do it almost anywhere, on almost anything. From rocks to figurines, classic canvases to stepping stones — use different paints on different surfaces to make your painted creations come to life! And with projects like Window Art or Sparkling Light Catchers from our Made By Me® line, you can use paint to create artwork that transforms sunlight into sparkling rainbows!

Keep Practicing!

You know the saying, “Practice makes perfect.” And when it comes to painting — strengthening your skills and mastering any technique comes with time. So, keep creating and experimenting with paints, techniques, and surfaces. Getting hands-on makes learning fun, and if you need some extra inspiration, here’s where to find it!
