sorry I misspoke by saying shades - the MacAdam's ellipses are measured for the same brightness so only apply to variation in hue/saturation. So I think we can see more shades of green but more hues/saturations of blue?
Another factor to consider is our acuity varies across that color gamut (see https://en.wikipedia.org/wiki/MacAdam_ellipse). So we're best at distinguishing subtle differences in blues and worst at seeing variation of…
