The Clarion has an astounding 728 selectable colours of illumination for the display and buttons. There's even a setting where these colours will cycle through.

…The Clarion was an absolute stunner as far as the RF and RDS performance goes. The designers seemed to have hit a really good compromise in all areas. It followed the transmitter change without a hint of muting and the combination of blending and treble reduction was spot-on.
…For the MP3 nuts, the Clarion has the ability to create a list of your favourite tracks.
…Opt for the Clarion is you're after a good performer, particularly on the tuner front and also if you like the idea of loads of different display colours.
