Color schemes for maps use the visual variables of hue, saturation and value to communicate information, sometimes in voluminous amounts, to a variety of audiences. Sensory-informed color schemes should also consider the manner in which a variety of organisms perceive color, as their perception may be an important factor in a number of ecological or evolutionary considerations. In this study, we look at avian color vision, a more complex vision system than human vision, and determine methods for how their color perception can be translated to color schemes for mapping. For example, avian egg colors vary from blue-green to brown along a linear trend that spans a tetrahedral color space. This avian color model is based on four sets of rods and cones sensitive to light in the long, medium and short portion of the visible, as well as the ultraviolet portion, of the electromagnetic spectrum. Once translated into human color vision, maps using such color schemes help reveal the role of colors in their behaviors and adaptions.
