Well I actually use Corel PaintShop Pro X8 instead of Photoshop, but you get the idea. I played around with replacing Yukei Kikuchi’s blue sharpie signature with a bright yellow. The version on the right is after a couple of minutes of using magic wand and flood tools to replace most of the blue with the yellow, and an hour or two of erasing stuff around the edges, painting in the remaining blue pixels with yellow, etc. I left in a blue edge around most of the yellow filling, which I think gives it a little more pop, although now that I think about it, adding a yellow edge to the blue might actually be the way to go. Not sure how much more I will mess with it but I like it and will probably print it up just for kicks. 🙂
