Hue, Saturation, and Color Modes

All right. Now let's see if we can clear out the last section of blending modes. The last section is right down here, and it's hue saturation color in luminosity. So Hugh means basic color. That means I'm going to take the basic color that I put on this layer, and I'm going to apply it to what's underneath. And so what those modes do is they divide your picture into three parts in that is hue, saturation and brightness. Where to describe any color in your picture. You could describe it as a combination of those three qualities. You can say the hue of that trailer is red. The saturation of that trailer, meaning how colorful it is, is high, and the brightness is whatever the brightness is. But those three qualities when I set this menu to the choice called Hugh, then whatever I put on this layer is on Lee going to change the hue of what's underneath. It will not be able to change the other two qualities that won't be able to change how saturated things are, and it won't be able to change...

how bright things are so I could click on my foreground color right now and choose, Let's say blue, I'll grab my paintbrush and I'm gonna paint and it's gonna change just the hue, meaning just the basic color of what's underneath. But it's not gonna be ableto modify the saturation or the brightness, which means if I paint over where the window is, the window is very dark, and that's part of brightness. Can't change that. The window doesn't have much color, which means the saturation is low. It won't be able to change that. It'll just be able to change the basic color of whatever shows up in there. And so I could come over here and try to change the color of this. You could use the any tool you don't have to be painting. Let's say I went to the radiant tool in the Grady Int Tool. I came in and chose one of these Grady INTs that had all sorts of colors in it. Here, let's make what it's make. A trailer that got rainbow of color. I'm gonna click near the left side. I'm gonna drag towards the right side, and unfortunately it's going to apply to the background to, But you can see the various colors going to cross will not get Listen, multiply modes if anything else is weird in here. Okay, there we go. It's applying to the wood as well. All that have to do is mask it. So it's not affecting that, Um but we can change the basic color of an object. Got a blue truck. You want to be read? This is how you do it. I'm going to create a new layer again. And this time I'm gonna paint once again and I can paint with the same color. And what I'm gonna do in this case, up some in the Grady into a well, I want to be in the paint. Brush is paint across things. In this time, I'm going to try something that is called saturation. Saturation means make the image underneath. Just colorful is when I'm painting with Well, that's not that useful here because if I choose saturation, it's not going to change the basic color. And it's not gonna change the brightness of what's underneath. It's on Lee going to change how colorful it iss so suddenly when I paint, I painted with a relatively colorful color and so covers that were in this wheel that was so dark that it was, you know, are so less saturated that you can hardly see it really come out then it doesn't actually shift the color of anything. So it's like, When is that useful? Well, one thing. It can be useful for all. Select on hit. Delete to remove the paint that's in there is if I paint with a shade of gray. If I paint with a shade of gray, it takes all the color out because it's trying to make the image underneath Justus. Colorful is what I'm painting with, and what I'm painting with has no color. So if you wanted to paint in areas being black and white, you could. One method of doing so would be to create a new layer. Set it to saturation mode in paint with any shade of gray. Doesn't matter which one, as long as it's a shade that doesn't have any color. There's no bluish or yellowish orange in there. Then we have another blending mode in here, and it is called color. Now. Color is a combination of two other bloody modes. It will apply both the hue and the saturation together, and so let's see what we could use it for. Well, what if I had an image that was black and white here? I'm just gonna choose de saturate to get this image to not have any color. It's an empty layer. We're gonna work in the layer underneath. Here we go. And so now, in this empty layer above, I'm gonna put some paint. It's a normal mode, so it just obscures your view of what's underneath. You might think that the mod called Hugh would work, but it won't because remember, this divides your image into three components hue, saturation and brightness. And when you're Hugh Mode, you're only applying one of those pieces, and it makes the image justice colorful of it was before justice, brighter, dark as it was before, while this image was black and white. If I choose saturation is not going to do it, it's on Lee. When I choose, color color means apply both the basic color that's in this layer and how colorful it is, and therefore the only thing that's picked up from what's underneath is the brightness, and so therefore, I can use this to colorize black and white pictures. I just probably want to be more careful with the colors that I choose. And so that is color mode. The last mode in here is called luminosity, and that means Onley allow this layer to change the brightness that's underneath make it so it takes on the brightness of what I'm painting with. So if we look for something where that might be useful, let's see, Let's look at a couple examples that in one other all right, here I want to apply an adjustment. I'm gonna come in and go to Curbs in and curves. I'm gonna dark in this picture and it doesn't matter that I'm using curves. It could be brightness and contrast levels. Anything that darkens when you darken the picture, you're going to find that the image becomes more colorful. Well, I wasn't trying to make it more colorful. That just happens without my wanting it to Well, if you want to, you can change the blending mode oven adjustment layer, and you can change it to the choice called luminosity. And that means allow this adjustment toe Onley affect the brightness. Do not allow it to affect the color at all. Therefore, it can't make the much more colorful, and it can't change the color of what's in the picture. So if I turn this off and on now, I'm darkening. But it's different because if I were to change this back to normal, watch the colors, you see him, how much more colorful they are. So when I said it to luminosity, I can darken without shifting or making the image more colorful. Another example of an issue here. Do you notice where the light is coming through here I can see a pink glow on the side here, kind of magenta ish, little purplish here and over here, a little kind of purple blue. Well, I want to create a brand new empty layer grab my paintbrush tool and all I'm going to do is take a color that's in the image where I don't see that glow. Let's say right in here and I'm just gonna paint over that. Take a color that's over here. You can do that when you're in the paint brush by option clicking. That means let me use the eyedropper tool just for the length of time you have option held down So if you're in the normal paint brush tool option clicking, which is all clicking and Windows allows you to grab a color out of your picture. So I'll do that. Now I'm gonna come in here and say Color, Let that apply to the color that's underneath, or I could set it to potentially Hugh. But you see how there I'm trying to get rid of those colorful issues. So when you end up going to the blending mode menu, you notice you have this long list of choices. It's less important to know what individual modes do. It's more important to know why are they group together in what's unique about each In this list, up at the top is an odd mode you rarely use called dissolve. That makes it so things cannot be partially see through. Instead, they'll either be completely showing up or completely disappearing in any area that looked as if it was partially see through gets this kind of dissolved look below that we have a section of darkening modes in those white disappears. It's known as being neutral, and so anything that's white completely goes away. Anything is darker than white has a potential of darkening. My picture multiply mode acts like ink. It's a good one to remember the next mowed down in there. It could only brighten your picture. And in those black disappears. Anything brighter than black has a potential of Brighton in your picture and screen mode acts like light. So if you remember that, you kind of get general mental picture of how those work the next section down combines darken. In Brighton modes, 50% grade disappears. It's what's known as neutral. Anything brighter than 50% grade takes on one of those lightning modes. Anything darker than 50% gray takes on one of the darkening modes, and so in their hard light mode, acts like light. If it's brighter than 50% gray in ink of its darker, the next section of modes compares the layer you're working on to what's under it and shows you where it's different with the choice of difference. It shows you that it's black, and if you try the other choices like exclusion, you'll find more gray showing up. But it's still comparing the layers and showing you where they're different. Then finally, the bottom set of blending modes ends up dividing your image into three pieces. And that is Hugh, which means basic color saturation, which means how colorful in brightness, which is how brighter, dark something is. And it applies only one or two of those qualities from the layer you're working on, and it grabs the rest from what's underneath. So the one and they're called color is the one that applies to it applies both hue and saturation. You're gonna find this menu not only at the top of layers panel. You'll also find it when you're in certain tools. You also find it when you're applying layer styles like Drop Shadow, orb, Evelyn and Boss and so don't think of it is just being a feature of your layers panel. It's any time you have an a piece that you want to apply to something underneath, and you wanted to interact with it in a unique way that's blending modes
