This is generated when what follow the rgb keyword may not be a valid
rgb triplet. It can appen in a number of ways, mostly when you apply
some arithmetics to your colour.
Normaly, it's safe to just ignore that warning. It can be used as a hint
when the colour you see is not what you intended or what it should be.
