Every variation that I posted on black background would work on a black background, yes. As would the white one. Although if you want to place
#31 specifically on a white background with the same colors, that may not work, so I'll need to adjust the colors. I can work on that. And of course you can get the white and black versions, that is no problem, you can get any variation you'd like. (Gradients, no gradients, different backgrounds, different colors etc...)
