RGB detection fix

I commented out the final line “show (result[‘shape’])” because that
was causing some Tkinter error. I played around with the colour ranges
and detections and made an extra new function (findIfRGB) that
determines what colour is detected. It uses the previously made
function 3 times. I did not feel like dissecting the original function
so the new function may be not the most efficient way of determining
the colour because it takes 3 pictures in one go. Also added an if
statement for the possible case where the pxlCount could be zero
(avoiding a divide by zero error).
