('viridis',
+'magma', 'plasma' and 'inferno') to R.  matplotlib is a popular plotting
+library for Python.  These color maps are designed in such a way that they
+will analytically be perfectly perceptually-uniform, both in regular form and
+also when converted to black-and-white.  They are also designed to be
+perceived by readers with the most common form of color blindness.  This is
+the 'lite' version of the more complete @code{viridis} package.")
