A method for constructing a colour space specific to an individual viewing a colour image on a display device, including at least the following steps: a first step of measuring an emitted spectral radiance; a second step of constructing a Euclidean colour space of the lights emitted by the display device; a third step of measuring, by computer, a luminance vector field perceived by the individual; a fourth step of constructing a model corresponding to the individual's perception of the colours.
