Hello!
Disclaimer: If you have experience in this area and think this would be over engineering a simple problem (that of good representation of magnitudes in the Z-direction of 2D histograms using colors) do share! I am a technical student at CERN who just started learning root this week.
Regarding root 5.
Is there anybody well-versed in root who could guide me through constructing and implementing a Color Palette based off the luminosity function*? Or have knowledge of previous implementations? If it has not been done I do believe there could be good interest for implementing it in future upgrades.
I’d like to implement the palette on images such as the one below.
I have only really managed the settings using the graphical interface.
*The luminosity function is a function, which unlike the rainbow color palette in root 5 which uses linear interpolation between wavelengths, has an adjusted interpolation to fit the human perception of color brightness to a specific wavelength: en.wikipedia.org/wiki/Luminosity_function
TIA
