Currently the theming is all over the place and changing one place does not affect any other. Although that kind of tweakability is great, most users just want different default colors. (pink, blue, brown, black)

What we should be having:
A: wallpaper - changes every release
B: color-theme - human (easily configurable by user!)
C: splash-canvas - human (we need to create this)
D: gtk-engine - clearlooks with B as default colors
E: kde-engine - oxygen with B as default colors
F: icon-theme - tango with color-filter using B

From these we could generate:
- grub-config using A, B
- bootsplash using A, B, C
- gdm-theme using A, B, C, D, F
- kdm-theme using A, B, C, E, F
- gnome-splash using B, C, F
- kde-splash using B, C, F

This way the most important customization people want, COLORS, will affect everything and keep it all one-look-one-feel. From boot to desktop.

Secondly, the art guys can create new engines, splash-canvas and wallpapers. All the specific appearance settings should be hidden under some 'advanced' button. By default, people change their 'engine', 'icon-theme' or 'colors' .. and this should affect everything from boot-to-finish.

Off course we need some magic unlock-button that turns your settings into system defaults.


I think it's also important to use the color scheme.

If this becomes a feature, any user could have a pink/red/black/blue Ubuntu just by changing the color pallete at the preferences window.
