I know that this is meant more towards design for digital screens, but I recently learned something interesting about black and gray tints when I was looking for colors to repaint some rooms in my house and ran across full spectrum colors. The theory behind this is that actual black and gray tints put in paints absorb light and most main stream paint colors use it to tone down colors. It does the job and is less expensive, and will make the color a bit more consistent in all light settings, but the colors tend to be a bit more muddy looking. This was why the impressionist painters generally didn't use black or gray tints directly. If they wanted a shade that looked black etc. they would combine tints from the ROYGBIV spectrum to create them which is why you see a bit of a vibrance in their paintings. Now that I've done a few rooms with the full spectrum and can compare you can definitely see the difference. Another fun benefit it that the full spectrum has more nuance depending on the light etc.. It is also why it is impossible to get an accurate color match of expensive full spectrum colors such as those by Farrow and Ball to try to save money with a less expensive paint. One is using several tints, the better ones a minimum of 7 different ones with no black and grey, while the standard paints use 4 (maybe 5).
