The help file for fourthcorner plainly tells you (sub Details). You can also
work out the meaning by looking at the summary statistics:

"The function plot produces a graphical representation of the results (white
for non siginficant, light grey for negative sgnificant and dark grey for
positive suignficant relationships)."
