When the pigment is spread out, light is allowed to surround the individual pigment particles, and in turn color shift is increased. However, when greatly extended, these pigments will appear as a grayish glaze, especially over white or light colored backgrounds. Blending Panspectra Colors Together Blending Panspectra colors together to create unique colors is possible because the intermixed colors do not cancel each other's shifting characteristics. Experiment with different pigment combinations and varying ratios to develop new Panspectra colors. The addition of familiar pigments, such as Quinacridones and Phthalos, is yet another way to expand the use of Panspectra paints.
Opaque colors diminish the color shift and intensity.
This does not mean one should avoid experimenting with opaque pigments. Transparent pigments tend to yield satisfactory results with greater ease and reproducibility. Extremely small additions of black will darken the color, but will maintain the original color shift of a particular Panspectra color. Thinner applications over a light color are not as intense as over a dark color. The addition of black can slightly increase the color shifting effect over lighter colors such as white.
