Truelight Colour Converter
Convert colours on the fly
Change the values in the fields below to view colours expressed in different colour spaces. Values can be displayed in either foot-lamberts or cd/m2.
Note that the Truelight Colour Converter calculates colour temperatures in u'v' space, and not in uv space. This may cause you to see unexpected values, if you are used a colour calculator that operates in uv space.
The Colour Indication swatch shows an approximation of the new colour. Note, however, that this may not be accurate as it is possible to enter values for illegal colours or colours that are not visible on a monitor.
