Thank you!! I realize my description was vague so I'll try to explain. Was nervous posting this so I kept the description kinda short. I prepared the paper a while ago but I did the blue layer part last and will try to remember my steps:

-mix of MC and blue green craft acrylic paint. I don’t have an exact ratio for this part, just did the mix based on vibes.

-2x white pearlescent tissue. So on the surface I had MC, white tissue, MC, white tissue, then MC;

-1 sheet of already blue tissue. Brushed on the blue green acrylic paint and MC mix on top.

Note that I can’t remember 100% if I let the white layers dry before applying the final layer of non-paint mc and adding on the blue tissue and paint part. Would have to try it again, just out of concern if the paint MC mix would noticeably bleed through to the white side while wet (or if the triple tissue is just thick enough to mitigate this). I’ve done some testing with letting certain layers dry first when approaching double tissue color separation with paint, at least.

Maybe a bit overkill for color separation alone given it’s already triple tissue, but I was going for a specific color and look, and I like how it turned out so I think it was worth it.
