A starting point. It looks like the LED color temperature (3700K+ for your bluing) are effected by the current applied to the LEDs. So most likely adjusting a resistance in the circuit powering the LEDs.

Luck;
Ken

very sorry, moderator.
i thought it would be packaged with third party firmware, since adjusting LEDs would be deep in.

Thankyou for that starting point, Rick. Can you PM me with where you think that control might be located within the OS? I will move this topic.

Hmm, Don didn't move my reply to your original post, so...
Quote:
None that I have every heard of. And it would require the LEDs in the device to be capable of changing colour. Or some other part of the hardware to be able to do this. I very much doubt the hardware is capable of doing this.
And hence I don't think the OS will support it. But, the OS is Linux, so you should be able to find how something like this is done in other Linux builds and test it.

The other way, which I think Ken was sort of suggesting, is to modify the hardware. If you can identify the circuit, you might be able to add a resister to change the voltage. This was done with the first release of the Glo to reduce the brightness of the LEDs. A search here should find it.
