Images couleurs pour l'enseignement de la colorimétrie, fondées
sur trois ouvrages de K. Richter, ainsi que les normes DIN et ISO/IEC.
All colour figures are in the folders MFXX (colour series M, F=français, 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
MF02
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 case),
see for examples the achromatic and chromatic test files according to DIN 33872-2 and -4:
33872E.html
or see the standard file with 1078 colours which produces for the four PS operators on the
pages 1 and 3 often different and on the pages 2 and 4 always equal output:
PE43L0NP.PDF
The most known software Adobe PDF-Reader produces at present with the default parameters
different output. However for the years between 1970 and 1995, and for example with the older software
PS- und PDF-Preview on MAC OS 10.0 to 10.2 (up to 2003) the output of the pages 1 and 3 was equal.
It seems still an open question to be discussed further, if this device-dependent software change arround
the year 2000 is appropriate for the field of image technology. This change seems not appropriate
according to ergonomic and colorimetric reasons.
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
Adobe FrameMaker (Version 8, Windows, 2011) the output is equal for all files of this web page. The software
Adobe Reader (all versions, Windows and Mac) produces different output. On the operating system
Unix the output is usually equal. The output is often equal, if colour management can be
switched off in the device driver.
The colorimetric difference in CIELAB increases up to delta E*=30 in the green and blue colour area.
A visible color differerence is seen near delta E*=1.
The many possibilities of the colour output lead often to a color chaos in the output. The
device-independent elementary hue output, and the 3D-linearization define only one output goal
which can be proofed visually at any time. This aim may reduce in future the colour chaos with
appropriate software and hardware.
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 the output of the pages 2 and 4.
This PS-program code uses the colour measurement data of 729 (9x9x9) output colours,
see the file output
PE43L0NP.PDF
One may study the spectral refection data of 729 colours within this file (1,2 MB, lines 3174 to 8644
for 5 papers and for the offset print).
PE43L0NP.TXT
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*)
The star (*) indicates a thee-dimensional 3D-linearization in the CIELAB colour space L*a*b*
for the CIE standard illuminant D65.

Order and download of the book Colour and Colour Vision
Many of the colour figures are from this book.
Members of standard organisations and teachers in the area of colour can order a free printed version, see
colorO
The printed book gives a much better introduction in the area of colour and its applications compared
to the internet versions. The book may be downloaded for a 3D-linearized output for the three devices:
display, offset print, and a laser printer, see
color.
