Roy G. Biv?

Hehe... that's for painters. For photographers it's RGB/YMC. I don't know of any mnemonic for that.

Wait a minute I've got a nmemonic for it... red, green, blue... yellow, magenta, cyan. That's easy to remember.

Wait, I thought the primary colors were red, blue, and yellow. That's not true in photography? Are they different for light than for pigments?

Roy G. Biv is what I learned in 5th Grade to remember the colors of the rainbow in order: Red, Orange, Yellow, Green, Blue, Indigo, & Violet.

In photography you talk about additive primaries and subtractive primaries. If you look at your tv screen with a magnifying glass, you'll see lots of red, green and blue dots. All the colors on the tv are made up of varying degrees of those three. If you look at a magazine page with a magnifying glass, you'll see a bunch of magenta, yellow and cyan dots (plus black for added contrast). On the printed page, the colors lay over top of each other and act like filters, subtracting light from the layer below. Painting with pigments is also a subtractive process... so magenta, yellow and cyan are sorta like the red, green and blue that you learned to use in school with paints, just more scientifically accurate. I hope that makes sense.

It occurs to me looking at this fine picture that you're good in a hurry, as this must have been a fleeting opportunity.

Lots and lots of the photos you see on this blog are taken on the run. Some even holding the camera out the side window of the car and releasing the shutter without looking. However, this one is not like that. I was waiting for my wife while she was shopping and I was entertaining myself by standing by a railing and shooting various shots of the escalators and various scenes 3 floors down. As we've discussed here before, stores have rules against such things. If you don't want to get caught at it, you need to keep moving. Standing in one place taking pictures for a while is a good way to get a visit from security. This particular time, day before yesterday I got a visit from a very, very nice store manager. She wanted to know if she could help me, etc... I told her I was just entertaining myself while my wife shopped and I would be happy to stop taking photos in the store.
