Color Selector
- When you click "start" the computer will randomly generate a color (RGB value) using the colors you selected above.
- The other colors are fixed to 0.
- Then you can guess the color.
- TODO: set background color of text message so they will be seen even if our color is black
- TODO: instead of typing in the number have a slider.
- TODO: show a color selector to make it easier to select.
- TODO: show the distance of the guess from the real color.
