instead of
LCD_RGBPACK(rb->rand()%255,rb->rand()%255,rb->rand()%255)
you can use
rb->rand()%LCD_RGBPACK(255,255,255)

Yes, but that would give the effect of random "flashing" colors, wouldn't it?

I set three "target color" variables (for red, green, and blue), and three "current color" variables. The current color in/decreases by one for each variable until the target color is reached for red, green, and blue. Once the target color is reached a new target color is generated with rb->rand()%255 for each variable and the process starts over. This gives the effect of "fading" colors.

Unless i'm not understanding you fully.. I'm fairly new with C :)
