Hi Gustavo, We've always known the current colour approach would prove inadequate at some point. The previous discussions (might find them in the archive) included trying to actually describe the sensitivity in terms of wavelength. Perhaps that is revisiting? in_intensityX_raw in_intensityX_wavelength_centre or similar? I see the datasheet conveniently provides a centre value for each sensor. Maybe it's worth considering how representative the full width half maximum value is of the data that we get for light sensors. Perhaps that ABI also makes sense? IIRC we do have a sensors with strong dual peaks though which makes this sort of description tricky.
