A colour-difference formulae would be based on a colour appearance model, but, So far, most
colour-difference formulae in common use are based on empirical fits to data. Therefore, of the many proposed,
none are completely satisfactory but advances have been made in recent years.
A new color-difference data set has been produced with the aims of making a comparison of the advanced
CIE Lab formulae as well as confirming the effect of color-difference. 416 low lightness pairs that have only
lightness-difference were produced for evaluation of CIE Lab-based formulae on lightness-difference from glossy
polyester fabric.
The standard color-difference pair was prepared and used. It was neutral grey sample pair that has only lightness
difference. The standard pair was used to investigate lightness tolerances. And grey-scale method used to evaluate
visual assessment. CIE Lab coordinates of the samples were measured using a X-Rite 8200 spectrophotometer.
Visual assessments were carried out using Gretag Macbeth The Judge Light Booth.
A study of color tolerances at low lightness was carried out and get avaliable some results. |
