Art clour test

When i had my painting back, and i look at it iam quite proud because the score is 8 out of 10 and i think its good for the first test that i done in art class. This task was about how do we mixed colour by using primary colours only, to mixed the colour that Mr.Pat(art teacher)gave us. I hjad paint 2 colours that were smimlar to the real colour. The colour that was left was quite difficult because sometimes i add too much blac. The colour that i paint is skin colours with many types. There are 4 types of the skin colours. I use yellow, red, white and black to make many kinds of skin colours.
