Looking at this diagram makes me want to transform the space so that the ellipses become circles. Is there any merit to doing that?


I guess this explains why a triangle figure was used in chromaticity page. How were these sensitivity measured? There are infinitely many ellipses we can make from this diagram as well, how were representative ellipses chosen?


On the chromaticity diagrams, it makes sense to me why we might see more regions of green because our eyes are more sensitive to it, but why would we also see larger ellipses in the green region?


Even for colors within the same ellipse, displaying them correct is still value if the goal is to show transition. Is there a metric to tell how smooth the transitions are?


How is the "just noticeable" defined, since everyone's eyes have different color sensitivity?


How was these ellipses calculated?


Are these ellipses defined in some mathematical way by the science behind the colors or are they just taken through some sort of human survey?


How do we traverse through points on the ellipse?


If our eyes are sensitive to changes in color, when we stare at a constant picture, shouldn't we fail to see the colors because the change in color of every pixel is zero over time? How do our eyes balance between changes in color and the actual color?


This there more color beyond this scope that some people may possibly see?


I am also curious about how this works. Is this based on experimental results?


Aren't these ellipses displayed here way bigger than the actual ellipses computed, for demonstration purposes?
