Ok, looking at your changes... I'm still not a fan of the stripes, but that's really up to you. It still has lime-green text on a teal background in a couple of places. You need contrast with text, otherwise it's hard to read. Make all the text black except where you're highlighting something, like where the words "red" and "blue" are red and blue. I'd also change the instructions box and button to something a little less bright, maybe a light blue, and put a black border around them.

Also, you should use the same color for all the info boxes. You need to keep things consistent. So instead of brown for the box after you win, make it same color as the instruction box. And is there a reason the box around the score needs to be purple? I'd say make it white with a black border, and make the score itself black. Although honestly I'm not sure you even not the box - just the red bar and the score would be enough on their own.

You're trying to do too much with the color scheme. Less is more. You want subtlety - not everything needs to stand out. You're making progress, though.
