Definition of spectral variables in the reflectance spectra of a C. umbratica male.
| variables | definition |
|---|---|
| UV intensity (RUV) | percentage reflectance (%) of UV reflection band |
| VIS intensity (RVIS) | percentage reflectance (%) of VIS reflection band |
| total intensity (Rtotal) | area under reflectance graph (from 300 to 700 nm) |
| UV hue (λ(RUV)) | spectral position of UV band peak: wavelength (nm) of maximal reflectance in UV range (300–400 nm) |
| VIS hue (λ(RVIS)) | spectral position of VIS band peak: wavelength (nm) of maximal reflectance in VIS range (400–700 nm) |
| band separation (λVIS–UV) | wavelength difference (in nm) between UV hue and VIS hue |
