  The New Horizons spacecraft mapped colors and infrared spectra across the
encounter hemispheres of Pluto and Charon. The volatile ices CH$_4$, CO, and
N$_2$, that dominate Pluto's surface, have complicated spatial distributions
resulting from sublimation, condensation, and glacial flow acting over seasonal
and geological timescales. Pluto's H$_2$O ice "bedrock" is also mapped, with
isolated outcrops occurring in a variety of settings. Pluto's surface exhibits
complex regional color diversity associated with its distinct provinces.
Charon's color pattern is simpler, dominated by neutral low latitudes and a
reddish northern polar region. Charon near infrared spectra reveal highly
localized areas with strong NH$_3$ absorption tied to small craters with
relatively fresh-appearing impact ejecta.
