Color land and water

The land and water parameters of pygmt.Figure.coast specify a color to fill in the land and water masses, respectively. There are many color codes in GMT, including standard GMT color names (like "skyblue"), R/G/B levels (like "0/0/255"), a hex value (like "#333333"), and a gray level (like "gray50").

import pygmt

fig = pygmt.Figure()
# Make a global Mollweide map with automatic ticks
fig.basemap(region="g", projection="W15c", frame=True)
# Plot the land as light gray, and the water as sky blue
fig.coast(land="#666666", water="skyblue")
fig.show()
