Do not know. However various colors do work differently on different armors witch is a real pain in the posterior
For instance white dye works great on some armors and not on others. My wife and I like to Transmog various armors over better armors and dying doesn’t work properly you can do a whole set in the same color and some will be the same shade. At this point recommend a contrasting color to accent. @AdisiTaliWaya
Test it on Single Player.
Spawn a thrall, spawn the armor, spawn the dyes and test. 
Cimmerians must use a lot midnight blue.
It also depends on your surroundings, some colors change in different biomes
This is the worst part haha
