- Formulate the Idea - Why am I doing this? What do I want to communicate? What's the point? Have a concept, a raison d'etre. It may change, but have one initially.
- Simplify the Shapes - Six to eight shapes. Lay 'em in.
- Average the Values - Four values. Decide and depict.
- Average the Colors - Each value shape becomes a color shape. Assign colors. Decide on relative temperatures.
- Determine the Extremes - Find the darkest dark, the lightest light, and the most dynamic edge.
-- How much detail?
-- How much information?
-- How much color variety?
NB: "Always make these modifications in relation to the extremes that you established. Nothing you add should be darker, lighter, more intense, or more dynamic than your established extremes."
