I presume it is some kind of pigment leakage....it's limited to some chips:It worked well with the AS $1.
The difference was only in the pink spots, and the yellow abraison seems to be a reaction of something with the pink color (?). Weird.View attachment 1305508

I think it's more time related (used pigments) and not color related since I have older chips (almond and Light Pink) that didn't show any signs of rust.
After seeing the BL pictures, I decided to sell my HSI $25 and opted for a different chip...don't want worry about rust in my chip cabinet.
