This lends itself easily to experimentation, what you need are:

A bucket or suitable vessel and that is a must.

Wall-type paint, a basic color, white suggested to begin with.

Concentrated liquid coloring agents.

A mixing stick - it is the hand of creation.

A camera, any will do if it works.

Experimental results cannot be duplicated, it would be like trying to duplicate the cerebral cortex. What you will perceive in the end will depend on your visual acumen, your power of imagination and your frame of mind. The more you will observe a "paint display" picture - preferably at diverse intervals and the more amazed you will be about its contents.

Just enjoy it, it will give you food for thought.
