Color Illusion in Practice
I talked a little bit about color illusion and joseph Albers a little bit earlier and of the relativity of color. And that's really what we're going to be focusing on in this series of exercises this afternoon. And this is his book. Um and we also have an ipad app. There's a great of ipad version of the book that is available that we're going to take a quick look at as well and maybe do some experimenting with. But this is also something that we're going to be using cut paper for mainly. Okay, so this is an example of what his book looks like and um, just kind of go back to this one. It's, You know, he has a lot of these experiments where we're trying to make one color look like two or two colours look like one experiments with the illusion of transparency and then applications using these same kinds of color concepts in Free Studies, what Albert's called Free Studies. Well, we might just call collage or something like that. Um but where you're employing similar ideas of say, how to ma...
ke yellow look different down here against the black. It has one kind of characteristic up there against the white. It has a very different kind of characteristic over there with the different the dark sort of brownish purple and the blues again, seeing these on different kinds of colours, enables us to go back and say, well, this is sort of a theoretical idea. Here's an actual in practice idea. Again, this great quote a in visual perception of color is almost never seen as it really is, as it physically is color the most relative medium and art. And that's kind of what we're here to prove this afternoon. Make one color look like to. So I showed you this before. Well, just kind of run through it again quickly. So you see the connection of the colors down below and the colours look dramatically different from one another. And there's a reciprocal relationship so that the X. That's against the blue green, the dark blue green looks like the background on the pink side and the X on the pink side looks like the background on the green side. And in fact, they're the same color. And it's kind of a middle color And then make two different colors look alike. What we call subtraction of color. So those colors, those two squares in the centre look very similar. They're not exact, but they're pretty close actually. Did this last night, my computer, but we see that they're actually two very different colors. So this is that and that is that. And you see how different they look on these backgrounds. So essentially what's happening is that the surrounding color is subtracting itself from the inside color. If you can conceptualize that it's kind of difficult. You know, a lot of my students, how do you subtract color? So you say, okay, light and dark. So a dark color. You put that on top of it, It's attracts itself, making it look later. The darkness is being subtracted from the color over here, the opposite. So this color, we put that on top. The lightness subtracts itself, makes it look darker. So that's a very simple principle and something that you'll be experimenting with.
