As you have been advised before, fltk-2 is deprecated, so support is likely to be "fragmented" - you would do better converting to the supported fltk-1.3 branch, I think. What version of fltk-2 are you using? What target platform? Is it WIN32? IIRC, WIN32 has some odd behaviours handling RGBA values if the A is 0, so that might be what's happening, I guess. Other than that, not sure, you would need to post a minimal compileable example that exhibited the failure so that we could consider what might be happening...
