colorrepel - Repel Visually Similar Colors for Colorblind Users in Various
Plots
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>.
