Yeah... .... Changes color depending on your comp settings, im on my sis comp and mines purple And the bars and headers...change depending on what you set, in your computer settings ^_^
he wants to know how to skin PS. long story short, you have to skin the entire computer for the most part. just get some computer skins and use those, windows blinds and other similar programs may work as well.
Its themes, photoshop displays your current windows theme, if you have the DA theme, photoshop has a green bg and different header bars.
Right click on your desktop and click properties, then u can change the look of windows in there and photoshop's theme will change too.
Or get windowsblinds or stylexp, I prefer windowsblinds myself, because tyle has a tendancy to f--k your system up.
You have to style Windows. Than it automaticly changes all your programms including PS. Like MTTVIPER said, use windowsblinds or stylexp
