With my home lighting being less than bright and no doubt less than perfect vision, I had trouble with the subtle variations in color. I should have paid more attention when ordering, but so far as puzzle quality, I was well pleased. (In the end, a full-spectrum lamp and a lot of patience paid off.) The glow in the dark feature was very nice.
