Figure 48: Color analysis view
Each color measurement is based on a scan from 360 nm to 830 nm. Therefore each color
measurement can also be expressed as scan by pressing on the icon
. Here the scan
can be viewed, zoomed and analysed.
Pressing the icon
opens the CIE XYZ color space as a Yxy transformation. The values
X,Y and Z are called standard color values or tristimulus values.
An absolute color space is a three-dimensional coordinate system containing all colors that
the human eye can perceive. Every color clearly corresponds to a point in the coordinate
system. The position of a color in the color space only depends on the spectral composition
of the light used and the absorption characteristics of the sample. All absolute color spaces
are based on the XYZ color space created by the International Commission on Illumination
(CIE).

The x coordinate represents the red component of the color and the y coordinate represents
the green component. The z coordinate is perpendicular to the xy plane and represents the
