Select a color on your dragon (other than the base color). That color can switch to another color at will. This is a bit like an on/off switch. Display will affect one color on the dragon other than the base color. Alternatively, it will affect a single trait (which might have multiple colors).
Display is a tricky thing to illustrate in one image, since it has to do with changing colors! If your dragon has display, you may provide an alternate version of their colors in the ref sheet section. You may also animate your design.
The markings do not glow–it simply changes like a chameleon or octopus.
Switches between blue/cyan and pink/magenta are allowed, but should not be quickly animated on the reference sheet due to the heightened risk of epilepsy reaction.
Color Rules
As a light effect, it will display over top-layer effects like albino and tobiano. In that situation, it will only shift between very similar hues of white, so that may not be too useful.
Modifier & Physical Trait Interactions
Display may not be affected by color modifiers directly. However, if the marking it is affecting is multiple colors, then the display will change the colors accordingly. It may affect wings, crests, and tails where the affected marking touches or in places where the selected color is.
Charged Display
Charged Display may affect the base instead of markings.
