Here's a screenshot before casting stoneskin. Note the color scheme, carefully chosen to mix the aesthetics of a x-man character and a 1980s VHS aerobics instructor.

Here's a screenshot after casting Shadow Shield, then resting. The resulting monochrome has no place in a Lisa Frank illustration or my heart.

When this bug occurs, the only workaround is to remove the outfit entirely then put it back on again, an annoyance which plays merry havoc with my spell slots and potentially my character's reputation.
