Select a color on your dragon (other than the base color). That color can glow at will. It does not change that marking’s color. If the marking would be black, it will glow with a gray color in dim lighting. This may be activated at will or kept on at all times.
Alternatively, it will affect a single trait (which might have multiple colors).
Color Rules
As a light effect, it will display on top of white mutations like albino and tobiano. The glow will match the color of whatever is beneath it.
Modifier & Physical Trait Interactions
Bioluminescent may not be affected by color modifiers directly. However, if the marking it is affecting is multiple colors, then the glow will match those colors. It may affect wings, crests, and tails where the affected marking touches or in places where the selected color is.
Charged Bioluminescence
Charged Bioluminescence can affect the base instead of markings.
