This is a drawing to illustrate the color wheel with three Primary colors(Red, Yellow, Blue) in the form of a sharp pointed sword. Three Secondary Colors(Orange, Green, Violet) which is formed by mixing the primary colors. Six Tertiary Colors(Sorry, Don't know the exact color Terms :D) by mixing each of the primary and the secondary colors.
I made a Tai Chi(Black and White) symbol surrounded by Grey outline to emphasis that the picture is all about weapon and supreme powers all colored in different shades of blade.
I was asked to draw a Color Wheel with some concept, this took about 3 hours with incomplete painting and lot of flaws all over it. This is my first art after a very long time i.e like after some 10 years. Will have to improve a lot in the days to come.
