Figures and data of "Colour difference data sets and performance of colour difference formulae" are in the folders YEXX (colour series Y, E=English, XX=00 to 99).

Folder and Title
Development of colour difference data sets
Many of the folders XEXX (XX=00 to 99) include colour difference data sets in the PS files. The files create a standard PDF output format which is used as standard input format in the folders YEXX (XX=00 to 99).
In the folders XEXX (XX=00 to 99) the input data of the colour difference data sets are from different sources. Any data set is described by 8 characters, for example OS_L0128.
1. O is for the name OSA, M is for the name Munsell, etc.
2. A or S describes the sample viewing condition: Adjacent (A) or Separate (S).
3. V, T, S, L, E is for the size of the mean colour difference in the data set
- V = VTCD Visual Threshold Colour Differences (0 < dE*ab <= 1)
- T = TCD Threshold Colour Differences (0 < dE*ab <= 2)
- S = SCD Small Colour Differences (0 < dE*ab <= 5)
- L = LCD Large Colour Differences (5 < dE*ab <= 20)
- E = ELCD Extra Large Colour Differences (20 < dE*ab <= 99).
4. 0, W, V, C, or D (0 = no pair comparison data used, or data from WANG or VIK experimental data used, or data from CIELAB or CIEDE2000 formula used).
5-8. number of colour difference pairs in the data set.

For basic information on colour, see also the booklet Colour and Colour Vision - Elementary Colours in Image Technology
in 6 languages: English, German, French, Spanish, Italian, and Norwegian (2015, 85 pages, 2,5 MB, PDF, format A5 also for mobil reading).
