The preceder to IC T C P, Ebner & Fairchild IPT color appearance model (1998), has a mostly similar transformation pipeline of input → LMS → nonlinearity → IPT. [3] [9] The differences are that it defines its input to the more general CIEXYZ tristimulus color space and as a result has a more conventional Hunt-Pointer-Estevez (for D65) matrix for LMS.
The IPT color appearance model excels at providing a formulation for hue where a constant hue value equals a constant perceived hue independent of the values of lightness and chroma (which is the general ideal for any color appearance model, but hard to achieve). It is therefore well-suited for gamut mapping implementations.
A range of increasingly complex color appearance models appeared to model the behavior of human vision under different viewing conditions, but ended up less used due to the added inputs required and overall algorithmic complexity. In addition, the performance of the 1976 color spaces under different viewing conditions is not their only problem.

Tom's son, Howard Tellepsen, became president of the Tellepsen Construction Company in 1940. In the 1940s and 1950s the Tellepsen Construction Company was awarded many projects that have become Houston landmarks, such as Ellington Field, Annunciation Greek Orthodox Cathedral, Texas Children's Hospital, [6] St. Luke's Episcopal Hospital, the Falcon Dam, and the Melrose Building.
