That depends on whether you're talking about additive or subtractive color...
Here's something I've always wondered:
Do humans all precieve colours the same way?
We all know that the sky is blue, but is your blue the same as mine? Do we know that your blue isn't, say my purple?
Trump says Hillary is responsible for color.
Yea, I've also thought about that. All I know is my color perception is the right one.
The waves exist, absolutely. But they only register as sound because we hear them.
The light waves also exist, whether or not we sense them, but they are not a 'color' until registered by a sense.
A deaf person who can 'feel' a Who concert is still processing the soundwaves (not sound) via a sense organ.
I was always told in Art that white is the absence of all colors while black is the presence of all colors
In Art (color) white and black are the absence of any chroma. They are on the gray pole at the middle of the Munsell Color system. Chroma increases as you travel further from the pole.
I know i'm being obnoxious. It is a hard concept to teach...especially when you have a white and black crayon in the pack. They may be different ends of the color spectrum, but there are still colors that we acknowledge as "black" and "white".
This thread is melting my brain! UGH why is the world so mystical????
I feel sorry for whoever is behind you in the Home Depot paint line
We can measure light waves - so color can be defined. We can measure intensity/Temperture as well - and is measured
in Kelvins. Colors have specific intensity ratings. Refractive and reflective qualities of light waves (which is what you are
addressing) are not indications of illusion.
We can 'fool' our eyes quite easily - but we can't fool a spectrometer. So the reflective red color off of a white wall - only
indicates the refractive qualities of the baseline color - not an illusion of color.
And the next step - now you are getting into why certain photographers are revered so much. They paint with light
and use the qualities to produce imagery that many of us find captivating.
We all know the medium is the message.
This actually takes us into the area of linguistics as well. I'm pretty rusty on the details and too lazy to google them at the moment, but it started with Benjamin Lee Whorf's color wheel theory (now pretty much discredited) but led to...aw look at that i googled it.
In his book "The Language Instinct" Steven Pinker writes:
the surface colors of A and B are the same. To test it out, just use your finger to cover the middle of the drawing, where the two squares meet.
Are the terminal points of the color spectrum used to paint with, obviously the answer is yes, just like the terminal points if a guitar string,,, except that the terminal points of the color spectrum terminal points are perceived as two things, black and white, and the two terminal points of a guitar string work together to create just one thing, a tone. But then the tone is actually like the white light made of all the overtones.
Similar because color and sound are both vibrating waves of a certain pitch, or hue.
Pitch and hue? The same thing?
That's amazing. It really demos the roll of our perception reacting to the context. It tricks our brain, and we can entertain ourselves for hours with the illusion.
Thanks for posting.
Bad joke I made up
Q, what do they call it when the color spectrum is not working?
A, a Hue Downs.
I'm sure that goes right over younger peoples heads, and trust me, it's ok.
Yes, but spectrometers are designed with our paradigm regarding color, that is, they are based on the human perception of what color is.
Please correct me if I'm wrong.
