Quoted from midcoastsurf:Scott Danesi was messing around with my RGBW frame the other day and figured out that you can dial in cool white to warm white if you select a color on the wheel, then hit the "W" button. For example, a blue, then W = cool white OR a yellow/orange/red, then W = warm white. It's essentially overlaying that color onto white.
If you want to reset to regular white, turn off the frame, and hit "W" to power it back on and it will go back to original white.
How is your frame different to the one the Stern sells?
