Blue prime
Blue (blue prime) is proposed for color-coding symbology, graphics and text with see-through or augmented-reality (AR) display systems—as well as conventional displays that are viewed under daylight conditions. There is evidence that Blue’ is more visible than blue yet retains the color name "blue".[1] This new color lies halfway between blue and cyan on a color diagram. Blue symbols and text can be difficult to see and read in moderate daylight. This difficulty is directly traceable to the lack of short-wavelength or "blue" photoreceptors in the fovea. There are two ways to implement blue’: 1. combine blue and green as 0080FF on a conventional RGB display, or 2. develop a new image source that replaces blue with blue’ as defined by chromaticity coordinates.
