THE TEST ABOUT ART

First i test about how much i know in colors, all of the question is easy eccept the last one. i did not do it really well ( you know it ask about what picture you gona make). Then 2 question is making color, my teacher gave us a color xample to everyone (no the same : and got a very tough one). And my teacher gave us color ( Red,Blue,Yellow,White,Black) and i try try try and try but i didnt get the color to be the same to the color xample. The tough thing is first it was light bule green color but the color i made is green ( like stinky) so at the end of the class i didnt get it at all. ( but i almost got it but then i mix to much blue so it turn in to dark dark green). The hard things is it hard to mix the colour, but many people in my class get it (not me) when i mix it sometime it almost right but after i try to mix it again to make it get closser it became stupid i mean: for example i mix it and it became blue green and after i mix it with bule it became blue blue green

ps: i was crazy at the end of class i mix all the color that i make and color it down
