There is an issue with colour blind people but also with a few tones of "blue" (or "green"). I had this argument in real life, many years ago, about what is called "petrol blue" in some car offerings, in front of the same car, I saw it as blue, and a friend of mine saw it as green. After long discussions, and having observed the car from all possible angles, taking into account the light, etc. we came to agree that it was BOTH blue and green. Try yourself a range (roughly) between RGB 07636E and RGB 1D4D6E. As an example here (set 22 steps): http://www.perbang.dk/rgbgradient/ http://www.perbang.dk/rgbgradient/
