Random Color

How I can make a change only Random color using lighter colors.

What I mean is that just want to use the colors that are in the upper right corner, I do not want to use dark colors.

Use this to the random color change:

startColor = new Color (Random.value, Random.value, Random.value);

You could set an array of colors, preset colors you can randomly choose. Or, you could set limits for the values of the rgb vector.

min r = x, max = y etc.
