This part of ISO 105 provides a colorimetric method for calculating an estimate of the magnitude (and optionally the direction) of the change in the perceived colour of a textile specimen when the chromaticity of the illumination by which it is viewed is changed. It therefore provides an estimate of the colour inconstancy of the specimen.<\/p>\n

\n

NOTE 1 Colour inconstancy and metamerism are related but distinct. With respect to a change in the quality of illumination,<\/p>\n

    \n
  1. \n

    colour inconstancy is the extent of change in the colour appearance of a single specimen,<\/p>\n<\/li>\n

  2. \n

    metamerism is the extent of change in the colour difference between two specimens.<\/p>\n<\/li>\n<\/ol>\n

    This part of ISO 105 therefore provides a method for assessing (a) but not (b).<\/p>\n<\/blockquote>\n

    \n

    NOTE 2 Comparison of the results of this method and those from visual assessments is valid only when the visual assessments are made<\/p>\n
