Do the different looks work like themes on cell phones?

If yes, then I was wondering if it is possible to make a bunch of different themes available? There are a bunch there that I like.

Mainly I like the ones with the crisp, bold colours rather than the more shaded, muted ones. This is primarily due to my somewhat degenerated vision. The deeper, bold colours are far easier to look at for longer periods of time.

Very well done!
