Colour
Fill each cell with a random colour.
Logic: Randomly decide with which colour to fill each cell. The colours are picked from the predefined set.
The Num Colours parameter controls the number of colours that are picked from, for example, when 3 is selected, colours 1, 2, and 3 are taken into consideration. The smaller the set the bigger the chances of picking each colour. With a set of two colours, there’s a 50% of picking each colour making it essentially the Draw experiment. With a set of three colours, there’s 33,3% of picking each colour and so on.
