Overall, I think the quiz has a really great concept, but I think it would be much more appealing if you included little color cards next to each color. I’m only saying that because the difference between ‘yellow’ and ‘dark yellow’ is quite subjective, and I don’t think the everyday person knows what ‘mauve’ looks like off the top of their heads (or at least I didn’t). I kind of have a quiz with a similar concept to your quiz with country flags in the tile format, which you can reference here, but if you could find a way to include the color cards in the current format of your quiz, I could see it doing really well!
Thank you for the feedback! Yeah, I knew that would be a problem when I was making it, but you're right, it would be improved with color. It doesn't seem like I can incorporate color into the quiz itself in this format. I could have possibly done that if I had better coding skills but I did include a link at the top to a color list so a player can use it for reference. And I also changed the names of the yellow ones.
