Yes, but the problem is specifically noted to be culturally biased in the
case of colors, and we did not want to try to adjudicate the definition of
blanu - this having been excessively debated to no avail.

UV is invisible, but is a color per se.  Some animals see it.  Likewise
infrared, which CAN be seen with the proper viewing devices.

Saying it is characterized by blueness is not saying that it IS the color
blue.  This is the old tanru issue of "blue house" incarnate.

No I can't.  THere are people who are into formall defining colors based on
theri positions on a  color solid, defined by (I think) those 3 properties.
I know of the definitions of no colors , or even what the typical values
are for each coordinate scale.  How you would use it, would be to put in
x2 the measurement numbers and an indication that the scales they are
measured on are hue/brightness/saturation.  How this would be done
is probably convention tied to whatever lujvo/fu'ivla iscreated.  But
leka broda li hue pi'e brightness pi'e saturation
is what I am thinking of.

I don't know what you mean by already then %^)
I presumed you meant being in the aftermath of no yet having done something
which is either ba'o or ba'opu'o depending on whether you are trying to
express that you've started or completed the action.
