CSS Gradients that avoid the “gray dead zone”
The problem with HSL gradients is that you now have a completely different color, and the whole thing looks like nothing found in nature.  Unless the rainbow is an intentional design element, it just doesn't quite look right.<p>It's useful, but not a substitute for really carefully picking your colors so it all works.<p>One of the harder things in creative projects is when you have two individual elements you want to use, but you don't like what happens if you add both.
