By popular demand (well, one request anyway) here are a number of button images you can use to link back to The Icon Bar. If you hold down the SHIFT key and click on one of the buttons you should get a save window.
Black
Oxblood (dark red)
Red
Orange
Yellow
Green
Cyan
"Baby blue" (the official TIB colour)
Dark "baby blue"
White
Background
As an added bonus, here's a background image of the logo too. If you use it on your desktop it doesn't really work in anything less than 32K colours - the RISC OS 256 colour palette isn't really subtle enough, even with dithering, so it has to be modified for 8- and 4-bit desktops. And yes, an Icon Bar theme is being worked upon for the RISC OS theme manager project.
