Why is O(n) red and O(n log(n)) yellow? Clearly, O(n log(n)) is slower. In general, whether a specific complexity is good or bad differs greatly based on what you're doing. I don't think it's a good idea to have the colors be the same everywhere. A particularly bad instance is how every single data structure is O(n), which is red/"bad".
