Changing Window Frame Colours

[Contro]

I've taken your advice, and installed all the relevant plugins and what not, but it seems very complicated to change the colour of the DDS images. I'm not great at photoshop...is there an easy way to alter the colours from one shade to another (with each shade matching the relevant "main" colour, if that makes sense)? I'm assuming there is...do you have, by any chance, a link to the info?

Thanks again!
