New theme_portinari(), a complete ggplot2 theme in the spirit of
Portinari's canvases, with three moods: "canvas" (raw linen, umber ink,
sienna contours), "guerra" (indigo ground, pale citrine ink) and "paz"
(golden cream ground, brown ink). Options for grid lines and a painted
frame; all text meets WCAG AA contrast.
New diverging palette terra_roxa: the plum and mauve tones of the worker's
shirt in Coffee Agricultural Worker against the pale greens of the coffee
rows, through a sage off-white center. Its colors were sampled from the MASP
image, and all nine are colorblind-safe.
New sequential palette roxa_terra, the companion to terra_roxa: from the
near-black soil at the bottom of Coffee Agricultural Worker, through the
plums of terra_roxa, to the pale citrine of Guerra. All eight colors are
colorblind-safe.
retirantes no longer draws on Mr. Queiroz Lima. Its light center changes
from #EFE9E0 to #D9CBB2, from Northeastern Migrants; the other seven
colors, their order and colorblind safety are unchanged.
Initial CRAN submission.
Discrete scales now work with ggplot2 < 3.5.0, which requires scale_name.
Palettes now have a style, as in RColorBrewer and MetBrewer: qualitative
(cafe, paz), diverging (retirantes, inah, sofia, guerra) and
sequential (guerra_azul, paz_ouro). portinari.palettes() and
show_portinari() gain a category filter.
New sequential palettes guerra_azul and paz_ouro, derived from the UN
panels.
Palettes are stored MetBrewer-style: colors in display order plus an order
ranking for discrete picks. Discrete subsets now suit the style: sequential
and diverging palettes keep both ends (and the light center), qualitative
palettes keep the most distinct colors. The colors returned for a given n
have changed for every palette.
sofia is now colorblind-safe for its first 3 colors (was 2).
New portinari.works() lists the paintings behind each palette with links.

first 4 colorblind-safe), from Portinari's Guerra and Paz panels at the
United Nations Headquarters.ramp order
stored with each palette, instead of the discrete priority order. Gradients
for every palette are smoother as a result.portinari.pal(), scale_color_portinari(),
scale_colour_portinari(), scale_fill_portinari(), portinari.palettes(),
portinari.cvd.check() and show_portinari().cafe, retirantes, inah, sofia. Two are colorblind-safe
for all colors, two for a subset.
