How about a theme for the girls?

However, while I love the Wild Mint theme, it's not so good for my daughter, who likes colours like aquamarine, purple, even pink.

No need; If you are being serious..
--you can adjust it yourself, or let your daughter adjust the colors to her own liking..

You can adjust the background color anyway you want, just by selecting it
right-click on an empty space on the desktop>Change Desktop background color , make any changes you want..

Let me suggest that you use the appearance option from Menu and the Gnome Colour Chooser (downloadable from Synaptic) to make modifications to your current theme. If you want to take it a step further you might consider using a wallpaper switcher like drapes or wallpaper-tray (both in Synaptic) to automatically change the desktop background graphics. Being mainly a Gnome desktop user I don't have any suggestions for KDE but i am sure there are similar options available there as well. Good Luck

The "Wild Mint" theme IS pretty cool. I use it stock as-is.
