A multicolor led panel.
I have been searching for a multicolor led display with no luck. I have thinking about making an alarm clock, and the person I am making it for has a thing for rainbows. So I have been wondering if anyone have ever seen an led display panel that can change its own colors.

Look for an RGB LED Matrix. You can find them everywhere. It isn't too hard to get an 8 X 8 matrix running on an arduino. Plenty of tutorials for it.

Was thinking more like 4 7-LED segemented or at least a 8 x 16 led matrix

A single arduino can handle that but you'll need to use a lot of shift registers to make it happen. Just a matter of using a couple of 8x8 matrixs. You can find several instructables where people have done this sort of thing.

Look through adafruit.com. They have a couple of OLED displays to use or rig up the display with rgb LEDs as ambient backlighting. Good luck.

Ah thanks, I found some. Been looking for something like that for days via google and other diy parts, and never saw one.
Its a bit more expensive then I thought but not of range. Although I might have to rethink how I might build it as my original arduino idea does not have enough pins to support them all.
