A Flexible Color Scale for Ternary Compositions

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" , Jonas Schöley, Frans Willekens (2017) "Visualizing compositional data on the Lexis surface" , and Ilya Kashnitsky, Jonas Schöley (2018) "Regional population structures at a glance" .
