can be added to the available process colors the choice of which neutral to include may depend upon the nature of the patterns to be reproduced patterns requiring the reproduction of dark colors e g deep burgundy navy blue forest green etc or black will benefit from a choice of black as the neutral colorant while patterns that require pastels will benefit from a choice of white or clear as the neutral to act as a chromatic diluent for the other process colors if seven or eight process colorants are available it is suggested that the blue cyan mixture again be maintained and a second or third neutral color taken from the group described above be added to the available process colorants with eight such process colorants a visually distinctive array of 36 colors can be reproduced using only the eight process colorants and 50 50 two way blends of such colorants it is also contemplated that as may be required by the target colors to be reproduced combinations of red and magenta or yellow and green can be developed and used in a manner similar to and as a substitute for the blue cyan combination e g as the u201c mixed u201d color in a five six seven or eight process colorant system thereby preserving the individual blue and cyan colors in those systems if nine process colorants are available it is suggested that the respective individual components of the u201c mixed u201d color e g blue and cyan should be substituted for the mixture with nine process colorants comprising for example red.
