Claim:
1. A method of adapting light using a lighting device that includes a color matching engine, a conversion engine, a controller, a processor programmed to execute each of the color matching engine and the conversion engine and operatively coupled to the controller, and a plurality of light sources each configured to emit a source light in a source wavelength range, wherein each of the plurality of light sources is operatively coupled to the controller, wherein at least one of the plurality of light sources is a white light, the method comprising: receiving a source color signal designating a selected color; determining RGB values of the selected color; converting the RGB values of the selected color to XYZ tristimulus values; determining a boundary intersect value, being a dominant wavelength of the selected color within a color space that is collinear with the XYZ tristimulus values of the selected color and XYZ tristimulus values of a white point, such that the boundary intersect value is closer to the XYZ tristimulus values of the selected color than to the XYZ tristimulus values of the white point; determining a combination of at least two of the plurality of light sources that emit a combined wavelength that approximately matches the dominant wavelength of the selected color, comprising the steps of: operating the combination of at least two of the plurality of light sources to emit an adapted light, which comprises the combined wavelength, wherein at least one of the plurality of light sources is the white light.
