Yet another raster. This time I made it into pie charts. Each pie chart displays its sub-divided areas amount of red, green and blue in relation to each other. White will therefore be made up of three equal parts of maximum red, green and blue. See for yourself.

I also made a polar area diagram raster. As the sectors will grow, or shrink, depending on the amount of color there will be more background, thus yielding a slightly darker image compared to the pie chart raster.
