Are we ready for some depthy, abstract conversation? Put on some gloves and roll up your sleeves. Let's dive.
As we sat admiring our Christmas tree, Anindeep and I had a curious conversation about color and perception. I posed the notion upon observation that our color changing Christmas lights only cast shadows on nearby objects when they were in a red/yellow phase, and that no shadow was cast when the lights were in a blue/indigo phase. This phenomenon reminded me of the ol' ROYGBIV spectrum we learned whereabouts grade 7, which comprises all the colors visible to the human eye. Too far "in the red" gives us infrared light, and too far beyond violet gives us ultraviolet light, both of which humans cannot perceive with the naked eye.
The inevitable Christmas couch time conversation came to this. What color would "new colors" be to us? How blown would be our minds to discover that we can perceive colors we've never seen before? It's so inconceivable, because all we know is currently based on our knowledge of ROYGBIV (or as my dad would say, "Crayola box of 8"). This is a wild connundrum to me, and it blows my mind whenever I think of it. I envision "new" colors to be like a puke gray/olive green for some reason, but I can only relate it and envision it based on what I know. In the furthest depths of my imagination, I might envision a "new" color as ALL colors, such as something that constantly flickers or changes, and as such one wouldn't be able to define precisely what color it is at any particular given time, and therefore its "new color" would be the flickering state, however you could define that.
We also discussed how color might be perceived differently by individuals. Who knows? And how can you prove it? I'm sure there's a biology and a science here that may undermine my next wonder... something to do with optical rods and cones in the retina. However, and regardless, what if red to me looks like blue to you? If I suddenly could jump in your head to see your perception, yet retain my own knowledge base of color, would my normal color lips look like they're purple or blue from your perception? Thereby you'd perceive me with purple lips and yellow skin as normal? Wild!
Another realm of color I find fascinating is Color Space. If you've ever utilized a graphics program such as Photoshop, you'll be familiar with this color palette. It's technically called "color space", a three dimensional diagram which represents the full range of known colors on an x,y,z axis:

The more red you get, the more positive the "a" factor; the more blue you get, the more negative the "b" factor. Likewise the more white you get, the more positive the "L" factor, and etc. What's also fascinating (as learned in the November issue of Professional Photographer magazine) is that this system was in development from the 1930s through the 1970s... way before Adobe Photoshop came into existence as we know it today... even way before the personal computer was personal. Interesting! In reality, we've been trying to figure out what Color is since the 1800s, which is when scientists discovered and labeled the primary colors as such (red/yellow/blue).
Analyzing color space, my new notion is that there are no new (humanly perceptible) colors in the world, but it is Time and the evolution of design which brings forth "new to us" colors for us to get excited about. Consider the 1950s' pastel and chrome color schemes, or the earthtones and avocado greens of 1970s contemporary design. Colors and designs are always changing, and technologies to access and recreate those colors are ever changing too. Since when did grey and white come to be stylish non-colors? Since Apple products. Also, have you noticed that there are new blues available now in Christmas lights? What! In recent years I've seen them in holiday displays, and the luminosity of those blues is striking! I almost can't believe those colors are existing before my eyes, and I can't figure how I am able to perceive them. Maybe they are bordering on ultraviolet spectrums.
Aside from design, color is a science I'm intrigued to learn more about. With color space, I have every color in the humanly visible spectrum at my fingertips to play around with. What about the humanly
invisible spectrum? How many more colors are there in the world? Do they go beyond infrared and ultraviolet? Is there supergreen or phenomenyellow? How do we see those?
Wow! My mind just blew up again.
