1. Method of configuring a lighting system comprising a set of at least 3 light sources (Li) with different spectra (Si(λ)), including a step of automatically determining the intensities (φi) of each of the light sources of said set by minimising a distance between a reference spectrum (SR(λ)) and a synthetic spectrum (SS(λ)) determined by the sum of the spectra (Si(λ)) of each source (Li) of said set weighted by said intensities (φi) in which said distance is calculated between a perception (PR,j(λ)) corresponding to said reference spectrum and a perception (Pj(λ)) corresponding to said synthetic spectrum, said perceptions being considered on a set of detectors (j) of a given observer.
