Yeah but this acrylic turquoise seems to be the right colour, not really sure x) but i'm pretty sure it could be nice on the mags xD
But you're right, it's hard to find the exact right colour ><
When I was looking for the right color at my local craft store, I took a piece of scrap foam from the MP MAG letters with me. I used that piece to compare to the acrylic paints and found almost an exact match.
