Create two lists of pictures, colors and text. 
Use BTN_A and BTN_B to select which list to use.
Use BTN_L and BTN_R to scroll, and BTN_U for random.
Use BTN_D to quit.

If the lists are the same lengths, you can use a 
single variable (constant) for the last index.
If the lists are different lengths, you will need to 
change the value of the last index.
