Chromatic and luminance contrasts of dispersed and non-dispersed fruits.
Scatterplot showing the blue-yellow chromatic contrasts (y axis) and luminance contrasts (x axis) between ripe fruits and upper leaf surfaces of dispersed and non-dispersed fruits. Reflectance spectra of ripe fruits and upper leaf surfaces were measured relative to a Spectralon white reflectance standard using a Jaz portable spectrometer and a PX-2 pulsed xenon lamp emitting a D-65 light source. The chromatic and luminance conspicuity of food items was modeled as a ratio of the quantum catch of photons incident on the retina by different cone types, using a dichromatic visual model based on the long-wavelength sensitive (L) photopigments (λmax 558 nm) and short-wavelength sensitive (S) photopigments (λmax 409 nm) possessed by Microcebus spp.
