All colour figures are in the folders MEXX (colour series M, E=English, XX=00 to 99).
The colours in the following files are defined by the free choise
of the four standard PostScript (PS) operators:
rgb setrgbcolor, cmyk setcmwkcolor, w setgray, 000k setcmykcolor

Many additional remarks and special examples.
The colours of the above files are defined by the free choise of the four standard PostSript (PS) operators:
rgb setrgbcolor, cmyk setcmwkcolor, w setgray, 000k setcmykcolor
Any file may use up to four different PS operators, see for example the file:
ME02L0N0.PDF
In addition some files are available in the languages German, Spanish, French, and Italian,
see for the rgb-data output
ME02
and for the cmyk-data output
ME52
There is software which produces for the corresponding colorimetric PS operators either equal or different output (often the

The output is equal, if the so called 1-Minus-Relation is used by the software (or the colour workflow).
For example for the new software

The many possibilities of the colour output lead often to a color chaos in the output. The device-independent elementary hue output,
The colorimetric calculations within the files use the 1-Minus-Relation for the output of the pages 2 and 4 and produce either
the device dependent device hues RGBYd (page 2) or the device-independent elementary hues RYGBe (page 4)
according CIE R1-47 for the rgb-data (1,0,0), (1,1,0), (0,1,0), and (0,0,1).
The special file output of the pages 2 and 4 produces for the following three devices:
1. sRGB colour display only rgb-data,
2. standard offset on paper L only cmyk-data,
3. laser printer on paper APCO only cmyk-data.
The final rgb- or cmyk-data of the output are calculated by an additional PS-program code within the file for t
This PS-program code uses the colour measurement data of 729 (9x9x9) output colours, see the file output

For the three devices there are outputs with the properties:
1. Transfer to device hue (RGBd)
2. Transfer to the elementary hue (RGBe)
3. 3D-linearization to the device hue (RGBd*)
4. 3D-linearization to the elementary hue (RGBe*)
