I don't much care for the yellow. If you have other colors, audition different ones & you'll probably find one you like that will go with it & make you happy. Is it laying on a green sheet or something? That may be throwing the yellow off in the blocks. Can you put the blocks on a black or white background to see if that helps to determine what goes better. I'm all for changing things up until I get what makes me happy. Be sure to let us know what you decide.
