If an image, for example a company logo is shown on different devices the degree of colour consistency amongst this set of stimuli can be defined as common appearance (CA). Because of the expanding number of devices with high dynamic range of imaging and with highly varying colour gamuts this issue becomes more and more important. Unfortunately conventional and established colourimetry, where usually two patches or images are compared side by side or through a media relative approach, is not sufficient, because the used metrics are developed for small colour distances. Establishing a measurement-tool for large colour differences and multiple reproductions side by side requires approaches that go beyond classic colourimetry. In this paper we designed a psychophysical experiment to measure if CA can be measured and we show a first approach for establishing a metric for CA through colour naming.
