i think a wiki with possibilities for Harmattan theming should be created considering the various requests... You maintain a huge number of colors and I can imagine the chore it is to tweak various files for each tweak... IMO a wiki with some pics and description of what the various .CSS files do would allow people to theme themselves instead of requesting... If we can get someone with meegotouch knowledge to do up a theme manager type of app where you choose elements and then enter the color codes, it'll be pretty handy... Sorry for the ramblings above i just was thinking aloud...
