Interference Colors

Definition

  • Liquitex® Interference Colors are colorless, transparent paints made from titanium coated mica flakes rather than traditional pigments. They are also known as "Opalescent Colors." They change their color (exhibiting a metallic look and color shift) depending upon the viewing angle. As the light hits the mica flakes, it either bounces off directly, reflecting the labeled color, or passes through to another layer and bounces out at a different refractive index displaying the complimentary color. The effect is visually similar to a thin coat of oil floating on water.

Application

  • Use in any technique or surface suitable for any acrylic paint or medium.
  • Apply straight from container, thinned with water or mixed with any Liquitex Acrylic Color, Iridescent Color, Fluid or Gel Medium to produce an endless variety of colors and effects.

  • Apply thin layers rather than one thick one.
  • Thin applications in a wash or glaze increase the visual interference effects.
  • To achieve a visually opaque coat, apply a base color that matches the "flip" or complement of the interference color, before applying the interference color. (i.e. Napthol Crimson underneath Interference Green).
  • To increase interference color effect, add 1% Mars Black to interference color.
  • To create iridescent grays, add 2-5% Mars Black to interference color.
  • Applied over white surfaces or light colors, they are translucent.
  • Applied over black or dark surfaces, they are seen as brilliant pastel colors.
  • Applied on transparent and translucent surfaces, they create unusual visual effects.
  • Mixed with Liquitex Mediums to create luminescent fluid glazes.

Characteristics of High Quality Acrylic Paints

  • Water soluble colors while wet.
  • Flexible colors when dry. Built-up surfaces will remain free of cracks and chips. Less flexible in cold weather. Softer in warm weather.
  • Air-dry by evaporation. Thin paint films: 10 - 20 minutes. Thick paint films: 1 hour - 3 days.
  • Surface of a dry acrylic painting can be cleaned by gently washing with soap and water.
  • Keep brushes wet. Clean up brushes, hands and palette with soap and water.
  • Little odor, no fumes, nonflammable. Uses non-toxic thinners and mediums.
  • Do not mix with turpentine or oils. Mix only with other acrylic emulsion paints or mediums.

Cleanup of Acrylic Paints

  • From hands: Wet or dried acrylic paint cleans with soap and water.
  • From brushes: Clean wet brushes with soap & water. Clean dried acrylic brushes with acetone, denatured alcohol or equivalent product. These cleaning solutions are toxic. Care should be taken during use.
  • From clothing: While paint is wet, clean with water and/or window cleaner. Dried acrylic paint is permanent on fabric.
  • From painting surface: While paint is wet, wipe with damp rag, clean with water. When paint is dry, simply paint over surface with desired colors and motif.
