Painting Wife’s Triathlon Bike

My wife really wanted to paint her 2009 Cannondale Slice.

This is what it looks like after the clear coat.

White and clear base.
Alcohol inks.
Spraymax 2k clear.

Unfortunately some spots that she used the pink on top of other colours turned brown after the clear coat.
I think they were always brown, but before the clear it was darker and looked almost black. The clear coat always makes things brighter, so then all of a sudden the brown showed.
She’s a little bummed about that, but not much we can do about it now
