Having trouble figuring out how to program the color you want? Then this is perfect for you. The program draws a bunch of color samples. Use left and right arrows to get the next batch. Use the up and down arrows to change the shade (up=darker, down=lighter) by 10. To change shade by 5, use t and b (mnemonic: under the 5 key), and to change by 1, use q and z (mnemonic: under the 1 key). When you find the color you want, click on it, and it'll tell you the color and shade to use.
