%description
Compositional data consisting of three-parts can be color mapped with a
ternary color scale. Such a scale is provided by the tricolore packages
with options for discrete and continuous colors, mean-centering and
scaling. See Jonas Schöley (2021) "The centered ternary balance scheme. A
technique to visualize surfaces of unbalanced three-part compositions"
<doi:10.4054/DemRes.2021.44.19>, Jonas Schöley, Frans Willekens (2017)
