ISO-CIE trend to a device-independent,
and elementary visual RGB* colour space
Remarks:
The relative elementary colour system RECS serves as reference
system of the visual RGB* colour system, compare
RECS.html.
For output examples according to the visual RGB* colour
system, see (900 KB, 10 pages) RECS09.PDF
Figures and data of the "ISO-CIE-trend to a device independent and elementary
visual RGB* colour system"
are in the folders KEXX (colour series K, E=English, XX=00 to 99).
