http://en.wikipedia.org/wiki/Thermal_radiation#Subjective_color_to_the_eye_of_a_black_body_thermal_radiator Contrast with this chart which are presumably the "true" temperature colours. http://en.wikipedia.org/wiki/Black-body_radiation#mediaviewer/File:Blackbody-colours-vertical.svg When does the eye percieve orange light as white light? Does it has something to do with the intensity of the organge light? Harry
