A method of controlling a light fixture comprising at least one light source emitting light having a spectral characteristic, a first color filter, a second color filter and a third color filter, each color filter has a predetermined spectral filter characteristic which gradually increases across said color filter, said color filters are independently movable and can be arranged in a number of different positions in relation to one another and in relation to said light, said method comprises the steps of: - receiving at least one color parameter relating to the position of said color filters and at least one color temperature parameter relating to the color temperature of said light emitted by said light source; - obtaining a resulting color of said light based on said color parameter, said color temperature parameter and said predetermined spectral filter characteristics of said color filters; - obtaining color filter position parameters indicating the position of said color filters in relation to said light based on said resulting color, said predetermined characteristics of said color filters and said spectral characteristic of said light emitted by said light source; - arranging said color filters in relation to one another and in relation to said light based on color filter parameters, wherein said step of obtaining said resulting color comprises the steps of: - emulating a light source emitting emulated light having an emulated spectral characteristic; - generating a resulting spectrum by applying said color filters to said emulated spectral characteristic according to said color parameter; and - obtaining (345, 347) said resulting color based on said resulting spectrum. - receiving at least one color parameter relating to the position of said color filters and at least one color temperature parameter relating to the color temperature of said light emitted by said light source; - obtaining a resulting color of said light based on said color parameter, said color temperature parameter and said predetermined spectral filter characteristics of said color filters; - obtaining color filter position parameters indicating the position of said color filters in relation to said light based on said resulting color, said predetermined characteristics of said color filters and said spectral characteristic of said light emitted by said light source; - arranging said color filters in relation to one another and in relation to said light based on color filter parameters, wherein said step of obtaining said resulting color comprises the steps of: - emulating a light source emitting emulated light having an emulated spectral characteristic; - generating a resulting spectrum by applying said color filters to said emulated spectral characteristic according to said color parameter; and - obtaining (345, 347) said resulting color based on said resulting spectrum. - emulating a light source emitting emulated light having an emulated spectral characteristic; - generating a resulting spectrum by applying said color filters to said emulated spectral characteristic according to said color parameter; and - obtaining (345, 347) said resulting color based on said resulting spectrum.
