1. A method for providing a non-uniform pigment distribution in a first plant part of a pigment generating plant, which accumulates pigment upon exposure by light, during indoor cultivation of said plant, wherein the first plant part comprises a second plant part and a third plant part, the method comprising:
in a first lighting stage, irradiating at least one of the second and third plant parts of the first plant part with first light that inhibits or prevents pigment accumulation in said at least one of the second and third plant parts of the first plant part, and
subsequently, in a second lighting stage, irradiating the second plant part of said first plant part with second light that promotes pigment accumulation in said second plant part while subjecting the third plant part of said first plant part to third light that inhibits or prevents pigment accumulation in said third plant part,
wherein, during both the first lighting stage and the second lighting stage, inhibition or promotion of pigment accumulation is achieved only through exposure of the first plant part to light irradiation.
