I probably only could change the Hue/Saturation and Brightness/Contrast, but I could try to do something. I suggest you request a banner from someone who can make them, 'cause I'd probably make a really sucky banner that hurts for someone to look at, but I'll try to do something anyways, idk if it'll work out though.
yeah, Ratiosu created it apparently? I think I'd better go and congratulate her on being able to create one (lol, I can't even customize a Proboards.com forum XP)
