This is really neat - thanks for taking the time to set it up. I wasn't having much luck with my mousepad, but once I got the hang of tabbing between colors and arrowing up/down for the values, it became really easy to tune the colors without even looking at the screen - just watching the LED's and keeping track of the tab movements.
My only thought - I wonder if it would be useful to have a 4th bar / slider which would adjust the intensity of all colors at once? I was playing around trying to match the SS light color and brightness to a set of incandescent miniature white lights, and then to a candle flame. Got the color pretty close, then went around about a dozen times and took a point or two out of each color until the intensity fell in line. A 4th bar for 'all at once' would make that a snap, too.
Either way, slick little app! Thanks!
