on many things including:

- Whether representing form or metric data ([Ware]_)
- Your knowledge of the data set (*e.g.*, is there a critical value from which the other values deviate?)

- Your knowledge of the data set (*e.g.*, is there a critical value
from which the other values deviate?)

- If there is an intuitive color scheme for the parameter you are plotting

- If there is a standard in the field the audience may be expecting

For many applications, a perceptually uniform colormap is the best

Colormaps are often split into several categories based on their function (see,
*e.g.*, [Moreland]_):

1. Sequential: change in lightness and often saturation of color incrementally, often using a single hue; should be used for representing information that has ordering.
2. Diverging: change in lightness and possibly saturation of two different colors that meet in the middle at an unsaturated color; should be used when the information being plotted has a critical middle value, such as topography or when the data deviates around zero.
3. Qualitative: often are miscellaneous colors; should be used to represent information which does not have ordering or relationships.
