The red of a rose
Is a succulent sight
Scientifically defined
By its wavelength of light
Is what you see
The same as for me?
My guess
Well, probably
Yes
But
If it were purple
I doubt it.
‘Colour Blindness’ is a misnomer. True mono-chromatic vision is rare in humans and usually the result of trauma. Most colour blind people are males who usually inherit it from their maternal grandfather along maybe, with a little baldness. What is true is that ‘colour blindness’ varies both in degree and in form and if like me, are only aware of it in three circumstances: naming, matching and discriminating. Evidently for me there is a low light colour shift- primary colours, no problem, secondary colours get tricky, tints and hues – confuse.
