Hi John, I am sorry not to use your beautiful description of the new system, but I felt that it would,be a bit of a mouthful,so after much brain damaging cogitation the option of Hypochromat seemed fairly apt, the 'Hypo' means below, "hence Below color" You have no doubt heard of Hyper chromatic effect where "hyper" means above, this is found in some systems where over correction happens, I found this on my research into dialyte systems where the blue and red foci are reversed.
