3D colour space comparison

However, only the following three-dimensional display of the colour spaces can show how well the colour spaces are actually covered.

Explanation: In the 3D views, the black grid represents the respective standard colour space and the white grid represents the monitor’s colour space. The intersection of both colour spaces is represented by the coloured cube. Where the black grid protrudes beyond the coloured cube, the respective standard colour space is larger than that which the LCD can actually display. On the other hand, if the white grid protrudes beyond the cube, the monitor’s colour space is larger at this point than the respective standard colour space.

ISO Coated: 100 % coverage

sRGB: 100 % coverage

AdobeRGB: 99 % coverage

Our guess that the monitor has an extended colour space was confirmed. Thus, the colour space of the Hyundai W220S covers the ISO Coated and sRGB colour spaces completely. The AdobeRGB colour space also benefits from almost complete coverage. Thus, in theory, with a suitable colour profile, it should be possible to work in any of these colour spaces.

The results of this colour space coverage are based both on the details from the "ICC3D“ tool, which we use for visualising the colour space comparison in the lab, as well as the results of the UGRA test. Although the latter provides considerably more measurements than "ICC3D", we achieved identical results via both processes.

deltaE deviation

Explanation of deltaE deviation: Deviation in colour values is measured in deltaE 94 (dE). Several grey gradients, the primary (RGB) and secondary (CMY) basic colours are measured. A deltaE value of 1 represents the smallest difference in colour that the human eye can perceive.

Most people recognise a difference in colour from a value of 3. However, our eyes are more sensitive to green hues, so smaller differences can be perceived here. The average deviation should be less than 3 dE and the maximum should be under 10 dE or, better still, under 6 dE. However, two colours are still sufficiently similar up to 10 dE.
