Overall, the quality is very good, the design is everything. It is neither too heavy nor too light. It is double-sided, which is a great feature. As for the colors, I would say the yellow is slightly lighter than it appears in both the product photos and my own (possibly due to camera limitations), and the brown is slightly darker than the pictures. Generally, I don't consider it a problem because there are always color variations between photos and reality, but in this case, it is almost negligible.
