All palette colors are available in liquid bottles. This can be used directly in your airbrush or used to refill the palette cells. To refill the palettes, first shake the bottle thoroughly until you can hear the mixing balls moving freely inside. Pour a small amount into the cell, gently stir while using the low setting of a blowdryer. When the color is almost dry, shake the bottle again ( it can settle quickly) and repeat the process until the cell is filled. Early on, the color Teak was in the original palette, but we substituted Cedar Brown in its place. However, Teak is still available in liquid form. We will continue to have liquids available of any color should they be replaced in the palettes.
