If you feel like adding a touch of color to your S60 phone then give the ColourFull Flow theme a try.
This free theme provides an interesting new treatment for the Symbian mobile interface. Instead of using descriptive pictures as icons, ColourFull flow relies just on a color scheme. Icons appear in a series of different colors and each has a word written on it that describes what it links to.
It's an interesting idea and the combination of an elegant font and glowing icon colors make ColourFull Flow nice to look at. Unfortunately, the color-coding system is very vague (if, indeed, it exists at all). What's more, much of the text on the icons has had to be abbreviated so much that it's often difficult to distinguish what they represent from a distance.
Besides adding these menu icons, the ColourFull Flow theme applies a new background wallpaper to the home screen - it's a bit dull, though. That said, I did like the new clock skin that comes with it.
ColoulFull Flow is a bit more original than most S60 themes, but it could've been implemented a lot better.
