Monochrome and temperature

- [Instructor] In addition to hue saturation and tone or value, you're going to also need to able to identify warm against cold colors. Let's go look at that right now in this movie. So here we have this ring of different hues. Now if I warm those colors up progressively towards the center of this diagram, you can see how that changes the values of the colors, especially if you look at the greens and blues on the left hand side.

On the right hand side a couple of those colors max out pretty quickly. Because, to be honest, red, magenta, orange, all are pretty hot to start off with. And red about as hot as you can get in terms of color. Going the other way, now, towards the outside of the slide here, adding blue makes colors cooler. And again, you can see where this is more prominent in the display of these colors here. You might also notice that the warmer colors appear to move more towards you.

And the cooler colors appear to be set back. And that's just a characteristic of warm and cool colors, that they advance or recede. Something else we could look at here is when we take color away. So, if I switch over now to this color image, beautiful mountain image here, and then remove the color from that totally, we've got a monochromatic image or here a monotone, whichever way you want to look at it.

But the tone or the chroma in this particular value happens to be black. Now there are other ways of representing monochrome images. You can use any color for monochrome. Here if I switch out to a pantone color, I've got this warm gray. That's the same image there. And you can see how that's presented. You can also produce tonal images mixing in your own inks and get some interesting results. So if I add to the pantone warm gray here, black as well, I've now got what's called a duotone.

And some of the tones in this image are tinted with the pantone, and the really deep shadows are tinted with the black. You can see, hopefully, how that's changes the dynamic range of this picture. Tritones, if I add another color, I'll add a sort of a yellow color here this time. So I've got this pantone one three five. And again, that's changed the values in the picture completely. And finally, a quadtone here, so four different tones and I've chosen to use blue 277 here and these are all really arbitrary choices.

I just want you to choose three different things to present this. You can have infinite variations of this, of course. But there you go. Those are the other concepts you need to get your head around. So warm and cool colors and also tonal images, including monotones, duotones, tritones, and quadtones. Sounds like a band I should be in.
