Fun quiz, (and I hate to be a downer) but I think that you missed 'jasper' for one. It's a reddish brown color...look up a picture on Google. It's pretty! I'm not bragging or anything though, if it makes you feel better!!
where is the h quiz? also, you could add some more colors to quizzes with fewer colors like the I one. also here is a website with over 30k color names in case you run out of ideas
