I have been teaching Rebecca about colors in code, and we made another little game to play with the idea. It gives you a random color and three sliders. Adjust the red, green, and blue until your color matches it before time runs out.
I wanted to connect the numbers to what she could see. We add up how far each slider is from the target, so the computer has a way to decide whether a guess is close enough. The countdown and score gave us some practice with timers and updating the screen. A little math, a little guessing, and a lot of colors.
