Unfortunately, the color display changes so rapidly it’s impossible to read and staring at it long enough to try to figure it out may actually give you a seizure. You can’t “lock” in a color once it has been established either, so it’s essentially impossible to see what the Hex code or RGB readings actually are. Too bad…with a little tweaking it seems like it could be a useful app, although basically right now, it’s a good idea, but that’s about it.
