orange is nice but others seem to be default xbtool preset genereator colors. I noticed if you do use their 'built in' blue/red/purple buttons it basically makes all the objects colors to similar, with not enough contrast. I've been tweaking my blue preset to match/blend with BlueGears EvoX skin. Will post them both once I have it down.
I just wish we had word when the presets will be integrated with AllXboxSkins.com (sorry, now I'm being redundant) I know they've been getting lots of user generated presets (you send it to them every time you use the tool). Lets just hope someone is filtering out the good and the bad. Also if we're creating a wishlist, It'd be great to be able to open up a .xbt in Xbtool preset generator to get a preview.
But better yet, I think our best bet is asking NightShd to include some sort of logo preview in his next xbtool in addition to displaying the colors. It's all ready better than the generator IMHO since you tweak the RGB/HSL precisely in Xbtool. Maybe if we all ask really nice he might consider it

In all serious he's done so much for the scene already with his tool and now maybe we're asking for too much...
