In a dark room, I can faintly see the emissions of some IR remote control LEDs (same with the IR data port on some Palms & laptops), and can tell when a button is being pressed or data is being transmitted. Many people cannot. Is IR a color then, or not? I can see it, poorly, yes, but some IR falls within my range of visual perception.
Which LEDs are these, and what are their IR wavelength range. Can you specify the manufacture.
I would like to measure them as see exactly what spectral radiation they are emitting.
What is probably happening is that the LED is giving off both IR and visible wavelengths.
'I'm pinging a color scientist on this. It will be interesting to hear what they have to say about this (science or semantics)?'
MMM should be very interesting
" Visible color as defined by the CIE, not necessarily everyone on the planet. The Standard Observer if you will. "
Is this discussion not about ROMM a colour encoding space derived from CIE colorimetry??
"Given that, I think it's a bit narrow-minded to define a "color" as something perceivable by human vision,..."
What or how would you define 'colour' then? This will be most interesting!
