If I know you right, I'd say it's more than just basic knowledge we're talking about ^^

Well, the skin do look flashy, so I can understand your reluctance to remove it XD And since it's still XP I suppose it looks flashy without having the oddities that is vista (judged from short in-store looks at it) which makes it even better.
I haven't happened to make any screenshot while having it black? Apparently not. My black variant is kind of nice, but if it's the same that you tried, I admit it is a little tricky to get to work. But not impossible in any way. And unlike the advanced skin programs this one's not stealing capacity ^^
