This is an update of my Desert2.0 color scheme. I changed quite a few elements.
It's important, however, that you use this color scheme with some other Workspace Appearance other than Oxygen (under System Settings > Workspace Appearance > Window Decorations) or you will not get the nice "canyon red" title bar color. I'm presently using Plastik.
Also, I suggest you install the 'Aya' Desktop Theme (under System Settings > Workspace Appearance > Desktop Theme) which will use your new Desert theme colors. 'Aya' no longer ships with KDE4x, at least in Linux Mint, so you'll need to download it using the "Get New Decorations" tab at the bottom right side of the window.
