A map is an information design object for which canonical colors for the most common elements are well established. For
a CVD observer, it may be difficult to discriminate between such elements - for example, it may be hard to distinguish a
red road from a green landscape on the basis of color alone. We address this problem through an adaptive color schema in
which the conspicuity of elements in a map to the individual user is maximized. This paper outlines a method to perform
adaptive color rendering of map information for users with color vision deficiencies. The palette selection method is based
on a pseudo-color palette generation technique which constrains colors to those which lie on the boundary of a reference
object color gamut. A user performs a color vision discrimination task, and based on the results of the test, a palette of
colors is selected using the pseudo-color palette generation method. This ensures that the perceived difference between
palette elements is high but which retains the canonical color of well-known elements as far as possible. We show examples
of color palettes computed for a selection of normal and CVD observers, together with maps rendered using these palettes.
