This is an interesting device that I have been trying to use in the same fashion for what it was designed, with a twist of how it is laid out. The standard color wheel divides up and clarifies where every color visible to the human eye can be placed on a map of how to get there. Thus I concluded it would be wise to try and use it for this same purpose.
The way that the wheel is laid out allows for the most important "heads" of categories to be displayed as new colors that are a result of the combining of other colors on the wheel. This allows for dividing the complicated multi-genric categories in authority position, for when art and music are equally mixed we get Green, or Animation which would be an artistic film with just music.
Then, the next important thing to note is that the Tone qualities of color can be utilized to divide up all of the sub-categories or sub-genre's of the staple title colors. Thus when it is brought up that there are many genre's within "Music" it can be easily clarified that they are just seperate tones, not seperate colors.
What are your thoughts on this concept?
