Game of Colors

Press 'Z' to pause the simulation. You can click on the pallet and add colors to the canvas. Use the color black to "erase" other colors.
'X' while paused to erase the screen. It takes a bit of time to avoid accidents.

After unpaused, the rules take place at each time step:

-- Any color with fewer than two same color neighbours gets color -1,
-- Any color with two or three same color neighbours mantains color on to the next step.
-- Any color with more than three same color neighbours get color +1,
-- Any backgroundColor with exactly three color neighbours becomes the color
-- Each color transition is associated to a sound. In every timestep the amount of each transition is counted and the sound of the most frequent one is played.
