# verdict [command...] [arguments...]

# Run the command given, colorfully showing its exit code on failure. On
# success, the exit code is 0, but it's not shown explicitly.

# A colorblind-friendly blue is used instead of green if either environment
# variable COLORBLIND or COLOR_BLIND is declared and set to 1.
#
# When variable NO_COLOR is declared and set to 1, an invert/highlight style
# is used instead of colors, no matter the exit code of the command given.
