No such thing as pink light?

So yeah, L249 is the new pink.

I showed this to my girlfriend and the first thing she said was "well I guess my new favorite color is minus green"

I believe those at Apollo disagree! ...

You're more en pointe than you know, young Chase. Apparently, Apollo doesn't believe in minus green, but does offer ~20 shades of pink/magenta.

...As stated, Minus Green has yet to accompany the other 150 colors/corrections within the swatchbook, but as film, photo and cinematography requests come in- we'll remedy this situation. ...

wow, that's surprising! well I better go rename all my color pallets!

[Grog12]

[eyeroll] does this mean I need to add minus red and minus blue to my pallet as well?

Not sure what the fuss is about. Many colors contain 100% of two of the three RGB primaries. Yes, back the green out any you have pink and then magenta. Back the red out of the group any you have cyan, back the blue out and you have yellow. We don't call cyan "minus red" and we don't call yellow "minus blue." (Except in old CRT TV drive circuit servicing!)

Well you can find blue and yellow in the visible part of the spectrum, whereas pink is not part of the visible spectrum. Nothing earth-shaking, our eyes/brains fill in based on what they see, but cool nonetheless.

In that vein, you could say that any color is "minus ___________" because it's missing some part of the spectrum, right? So black would be "minus everything"? Don't these people have anything better to do?

So really, "Pink" is synonymous with "Minus Green" so we can just continue how we were before this video.

Just to be clear. This is only true in TV's and LED lights, not true with incandescent lamps and gel. (subtractive vs additive mixing). There is single EM frequency which our eyes and brains see as 'yellow'. I can generate this response in your brain with that frequency or by a mix of others (like red and green). The point of 'there is no Pink' is that there is no single frequency of light that your brain will see as pink (or Magenta for that matter).

On another note, last weekend a client asked me to change the LED color from purple to "clear." So I shut them off. She meant white.

Well, our eyes actually only see RGB as that is what the cones respond to (Or B & W for the rods.) Yellow looks yellow because it stimulates R and G cones. Therefore, yellow can be either one frequency in dead center, or two separate frequencies coming in on the R and G axis. As for the spectrum, the output of a prism will only display full saturation colors. ROYGBIV is the trick to finding pink, it exists in the cross-over between V and R which is an octave jump. Look at the very bottom of the visible spectrum and you will see full saturation magenta right before red. Lower the saturation by adding the full spectrum and you have pink. Since it exists right where the jump occurs, I can see their point somewhat.

The best example of us being thrown off by the octave jump is the old Roscolene color "Surprise Pink." Indeed, when you looked at the gel it looked lavender. When put on a light, Surprise!, it was pink! In this case, getting enough quantity of light to provide proper stimulation of the cones from a full spectrum source provided the surprise. As with flesh colors, any deviation becomes exaggerated, so viewing the gel in dim room light, or a broken spectrum from a florescent light, or double passed (such as laying on a piece of paper) gave it a whole different color!
