 This will produce a single colour for passage between 1500 and 1600 m and between 1800 and 1900 m, and leave all other passage, above, in between, and below, uncoloured. This will produce a single colour for passage between 1500 and 1600 m and between 1800 and 1900 m, and leave all other passage, above, in between, and below, uncoloured.

 +The default altitude rainbow is not made with a continuous range of colour hues. Instead, it is made with 7 discrete colours, with altitudes between them fading between the discrete colours. This means that you can use a lookup table to exactly replicate this colour behaviour, using the following colour values which match the default ones used by Therion (shown here within the range of altitudes from 4 to 96 metres):
