This graph, from [1] shows that the L cone's responsivity doesn't go back up at all toward the left:
https://en.wikipedia.org/wiki/File:Cones_SMJ2_E.svg https://en.wikipedia.org/wiki/File:Cones_SMJ2_E.svg It is lower at 425 than at 450, which makes sense.
Now what does this one from [2] mean https://en.wikipedia.org/wiki/File:1416_Color_Sensitivity.jpg https://en.wikipedia.org/wiki/File:1416_Color_Sensitivity.jp... (logarithmic scale or not)? The "Red cones" Long line says "absorbance" is higher at 425 than at 450.

- jacobolus 8y agoYour second link is on a log scale. The left tail of that long-wavelength cone cell response is not related to the bump in the X of the XYZ color matching functions.
- cosarara 8y agoI know it is on a log scale. This shouldn't change whether it goes up or not, it should just change how much it goes up (or down), visually.
