Use single colour ramps to display ordinal data (categories, ordered). Single colour ramps must only be used when there is a logical order to the different levels of the variable. Single colour ramps must not be used for ordinal data (multiple categories, no order. E.g. gender). Use the blue colour ramp first. Of more ramps are needed, add other colour ramps in order of appearance. For fewer than 7 steps, use colours up to the corresponding number. When displaying text on top of the colours, use black or white as indicated.
