If the underlying data representation was HLS rather than RGB, doing this
would not be ludicrous - it would be expected. OTOH, if the underlying
representation WAS HLS then doing something like taking all the green
out of the picture - then putting it back without affecting the hue would
seem ludicrous.
(Sorry - that should have been "...putting it back without affecting the RED
would seem ludicrous.")
