A script rancolors displays random colors in the Figure Window as shown in the Figure below. It starts with a variable nColors which is the number of random colors to display (e.g., below this is 10). It then creates a colormap variable mycolormap, which has that many random colors, meaning that all three of the color components (red, green, and blue) are random real numbers in the range from 0 to 1. The script then displays these colors in an image in the Figure Window

% these in a row vector "image"
