A method of iteratively adjusting a color of light emitted by a light source includes setting a weighted target color to an initial color of a light emitted by a light source. The method further includes determining a target color of the light by a color controller to iteratively adjust a color of the light to the target color of the light. The method also includes determining an updated weighted target color as a combination of a portion of the weighted target color and a portion of the target color. The method further includes adjusting the color of the light by the color controller to the weighted target color.
