Re: Colour, Colour, Colour.

ShadowLight,

Those are pretty harsh words for someone who is so generous with her knowledge. I think it's worth noting that being a good self promoter is a pretty essential skill for any retoucher looking to make money from their craft.

Now, you say there is "no chance in hell" that green/pink or red/cyan make up complementary colors. I heartily disagree.

I suggest you take a look at the following link:
http://en.wikipedia.org/wiki/Complementary_colors

You could get the same results by going into Photoshop and taking a pure red and inverting it to get cyan or a pure green and doing the same to get magenta, aka pink.

You can also try the experiment of placing a cyan layer over a red layer at 50% opacity. You will get grey, which is the definition of a complementary color.

I'll accept that in art class we all learned that red and green, blue and orange or purple and yellow are complementary. I also accept that as being correct as far as painting and subtractive color models go. But most of us work in RGB, which is an additive color model, and knowing that less red is the same as more cyan is pretty useful.

If you're going to assail someone's credentials you had better get your facts straight first.

Tim, I stand by my words.

If you open any book on Colour Theory you will see this: http://en.wikipedia.org/wiki/File:BYR_color_wheel.svg

Red complements Green no matter how you slice it.

This model is based on the visual perception of colour.

The first cells we developed help us judge temperature which we perceive as blue-orange. Later we evolved the second set of cells that allowed for red-green colours to be perceived. Or so the story goes.

even so we don't necessary actually see the same,
but still judge temperature the same way. you may find this interesting:

again... bad information is worse than having any.

taking it from someone who has obviously never opened a book on it is a problem, assuming that it comes for a competent source just comes from a good "sale"

... and I have seen her work, and stand by my assessment of it.

I think you misunderstand me.

You are right in so far as Red and Green are complementary. In fact the color wheel you linked to was on the page I linked to.

Where I disagree with you in the assertion that if Red and Green are complementary colors Red and Cyan cannot be. Both cases are true, they are simply dependent on the color model you are using.

We work on an artistic level and a technical one. I know orange and blue look good together. I also know that if I make a curves adjustment in Photoshop while in an RGB space and pull down the mid tones on the Blue channel then the image will shift towards yellow, not orange. If I pull down on Red the image shift towards yellow.

We have to learn to see color but also how to think about color and work with it technically. We therefore need to work with both perceptual and technical models. Hell, with Lab I'm not even sure what to call some of the primary colors but I know what happens if I push the color channels one way or the other.

Don't get caught up in pedantry. There's many ways to slice a color wheel and more than one of them is useful.

Adobe Kuler comes with Photoshop. You can find it under Windows - Extensions. However, understanding the thing is far more useful.

Here is another color wheel (based on LAB with four primary colors, magenta , green, yellow, and blue) that you may find useful.

There is NOTHING NEW in visual world. Everyone is standing on the forerunners's shoulders. Michel Eugène Chevreul, a French chemist, anticipated LAB color in his seminal 1839 work, On the Law of Simultaneous Contrast of Colors. He tried to describe something that is even today indescribably complex— the propensity of the human eye to break colors apart from their surroundings. The effect had been known to some extent by the ancient Egyptians, and in the 15th century Leonardo da Vinci indicated that he understood it. Three hundred years later, the brilliant German poet Johann Wolfgang von Goethe expounded on it, and it took less than a century thereafter for Chevreul to fully flesh it out.

Kuler is great, I use it all the time. You can also access it online to create your own 5 color swatches which can then be exported as an Adobe swatch file to import into creative suite apps.

You can spend a lot of time playing with it and trying different color combos. I've even used it to pick paint colors for my apartment.
