An older chart that I keep in mind as a reference when doing saturated colors. 

All of the colors are at 100 saturation 100 brightness.   The grayscale is how they look in proof preview under a grayscale device simulation. The numbers are the brightness value of the grayscale version. So the bright yellow is like a 97 brightness gray while a deep blue is around 27 brightness.
