> I wrote this program that hooks up to a webcam. It takes a photo out the window every five minutes, and it will upload that to a server. The server then reads the sky portion of the photo, and it goes pixel by pixel. What it does is it takes all those values, the RGB values, and it averages them. So what you are seeing is not the dominant color in the sky it’s actually just the average color.
