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 [[Color management#Gamut mapping|gamut mapping]] implementations.

[[DolbyITU-R Laboratories]]BT.2100 has proposedincludes a color space, dubbedcalled [[''ITPICtCp'']], which they say improves the original IPT by exploring higher dynamic

range and larger colour gamuts.<ref>
