The discrete rainbow colour scheme is inspired by the temperature map of the weather forecast in newspaper de Volkskrant: unconnected curves in CIELAB colour space for purples, blues, greens and oranges, each sampled three times but the last one twice extra for yellow and red, in total 14 colours. The curves were straightened, shifted and sampled equidistantly to make the colours more distinct, reasonably colour-blind safe and print-friendly. Later, the lines were resampled with smaller distances and the scheme was extended towards white and black, to get 23 colours. Figure 21 shows how the two sets can be combined to make a scheme with any number of colours up to 23.
If you have an application where one of the colours stands out too much (for example colour 18), use a set with one extra colour and skip the unwanted colour. A discrete scheme with even gentler steps can be constructed by interpolating the smooth rainbow colour scheme above in large equal steps. However, these two alternatives make it harder to identify which colour is used in a given map area. Figure 21: Discrete rainbow colour scheme for maps, with 1 to 23 colours. The numbers refer to the colour definitions in Fig. 19.

Figure 23: Diagnostic maps for the discrete sequential schemes given in Figs. 17 and 19. For each scheme, the section at the left contains all colours, while each of the other sections contains one colour with one diamond of each other colour. This tests how well the colours are identifiable.
