Interface colors in XP ? how?

ok they give the silver, olive green, and default blue and some others in the XP+ pack thing, but can you change the colors to make your own like in the classic style UI. Like lets say black?
Can the colors in the new interface be changed to what you want to see or do you have to buy ones MS makes, that doesnt seem right ?
I dont mean the sounds background login screen and all they other components that make up a "theme", just the taskbar colors, window colors, colors in general in the new UI, how can this be done if at all ?

[quote]TGT Software has come up with a new program called Styles XP and Style builder. Styles XP addresses the issue of MSSTYLES (visual style) files and the need for them to be digitally signed by Microsoft. It replaces the UXtheme.dll file with a hacked version of the file that eliminates the need for a digital signature. Included with Styles XP is a visual style they call "toothbrush" which is a sample MSSTYLES file that they created showing that no digital signature is needed. Later this month they will release a program called Style builder that will allow you to create your own visual styles. Until then, you could use <a href="http://www.rpi.net.au/~ajohnson/resourcehacker/" target="_blank">Resource Hacker</a> to replace the bitmaps in the MSSTYLES files to make your own visual styles. I am currently working on a TweakXP.com visual style that I will post in the next few weeks. <hr></blockquote>
