Abstract: The invention relates to a method for configuring a lighting system including a set of at least 3 light sources (Li) having different spectra (Si(?)), including a step of automatically defining the intensities (?i) of each of the light sources of said set by minimising a distance between a reference spectrum (SR(?)) and a synthetic spectrum (Ss(?)) defined by the sum of the spectra (Si(?)) of each source (Li) of said set weighted by said intensities (?i).
