%description
Iterate and repel visually similar colors away in various 'ggplot2' plots.
When many groups are plotted at the same time on multiple axes, for
instance stacked bars or scatter plots, effectively ordering colors
becomes difficult. This tool iterates through color combinations to find
the best solution to maximize visual distinctness of nearby groups, so
plots are more friendly toward colorblind users. This is achieved by two
distance measurements, distance between groups within the plot, and CIELAB
color space distances between colors as described in Carter et al., (2018)
<doi:10.25039/TR.015.2018>.
