Explanation / Answer

Then create a random generator:

As colours are separated into red green and blue, you can create a new random colour by creating random primary colours:

Then to finally create the colour, pass the primary colours into the constructor:

You can also create different random effects using this method, such as creating random colours with more emphasis on certain colours ... pass in less green and blue to produce a "pinker" random colour.

Or to ensure that only "light" colours are generated, you can generate colours that are always > 0.5 of each colour element:

There are various other colour functions that can be used with the Color class, such as making the colour brighter:
