Sort of. http://www.allprofitallfree.com/color-wheel2.html 100, 100, 100 is Grey actually. But yes, it's an even mixture of red, green, and blue. You can use rgb(Number, Number, Number) or the normal #000000 system for any color you want. That specific line refers to the background color of the thumbs down button which is a dark gray color. White is rgb(255, 255, 255) and black is rgb(0,0,0). rgb(0, 100, 0) is a dark green. Use the color wheel above.. find you a color you like, and have fun with pyRadio. The beauty of open source . Just remember that if you update from me your changes will be lost.
