I actually has this exact thing happen to my tattoo. Only in the black ink. My artist has no idea and never seen it before either. But mine look exactly like yours. I've had my tattoo for almost 2 years. Bizzare af!
Got my back outlined by Scott Sylvia last weekend. East meets west style mashup of a reaper and koi. As usual, he FLEW through it and crushed. Lined the whole back and butt cheeks in 3.5 hours.
I go back for two more sessions in June, then we'll figure out the next steps after that.
I'm not really posting full photos anywhere until it's done, but will circle back here if I decide to post any detail or close ups. I have sent to people on IG, so if we're friends and you're curious, hit me up.
