LOL doubt it.
 
Rods and cones (something like five different types I think I read at last count) respond to specific wavelengths within the visual range. The brain constructs the combinations to provide the visual image we perceive. Visual perception is an incredibly complex process, involving the visual cortex, the limbic system for emotional reaction and autonomic responses (fight/flight) and the language and pre-frontal cortex to provide the meaning interpretations to behave beyond the reactionary level. Most animals don't have the last two to any degree that we can recognise. "Colour" is a word, just like we use words to describe sound, e.g. high, low, bass, treble, rumble, piercing, screech.

Or did you mean something else?

Some psychopaths become serial killers, and other psychopaths become prosecutors. - Bob Ruff, Truth and Justice, June 2016

Sooner or later, I hate to break it to you, you're gonna die, so how do you fill in the space between here and there? It's yours. Seize your space.
