\fB\-k\fR [zhxrlv]
Black value target: z = zero K,
h = 0.5 K, x = max K, r = ramp K (def.)

The colors to be translated should be fed into standard in,
one input color per line, white space separated.
A line starting with a # will be ignored.
A line not starting with a number will terminate the program.
Use \fB\-v0\fR for just output colors.
