scope:

Describes minimum ergonomic requirements and guidance to be applied to colours assigned to text and graphic applications and images in which colours are discretely assigned. The specifications in this part thus exclude photorealistic images and graphics. This standard applies to both display hardware and software because both these sources control the appearance of colour on the display screen. The specifications measurements and test procedures described in this standard part are for displays that produce colour images and are intended to be independent of display technologies unless otherwise specified. The specifications in this standard part are for images on computer displays that meet minimum requirements for users with normal colour vision. Displays conforming to this part will be sub-optimal for persons with colour vision deficiencies. This standard is complementary to part 3 of ISO 9241. The tasks and conditions of use in this part are similar to those described in part 3, unless otherwise specified. This standard part is not intended to be a specification on colour coding which is covered in part 12. Although the primary users of this standard part are intended to be hardware and software user-interface designers and manufacturers, it will also be useful to those persons responsible for procuring colour displays and those evaluating the use of colour in the user-interface of the computer system.
