On second look, this does not make sense. Suppose we are starting of
with a channel strength of 1A for blue, we can then obviously only going
down to 00 which would be -100%. +100% should be 2B. SO we are not
allowing this to be turned up even further?
If we are allowing -100% we really should at the other end be open (or
at least go to _much_ further.
