Six distinct states are identified and assigned a color:
? Information: (White) - considering purely what information is available, what are the facts?
Emotions (Red) : instinctive gut reaction or statements of emotional feeling (but not any justification)
Bad points judgment (Black) : logic applied to identifying flaws or barriers, seeking mismatch
Good points judgment (Yellow) : logic applied to identifying benefits, seeking harmony
Creativity (Green) : statements of provocation and investigation, seeing where a thought goes
Thinking (Blue) : thinking about thought
The design is simple but illustrates the concept perfectly. The slides are also editable so that you can adjust the graph, edit the text, or change the colors as you like it.
