TernaryCenterGrid

Return Ternary Gridlines Centered Around Some Composition

internal

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

to visualize surfaces of unbalanced three-part compositions"
