Now, let us say that you do not want to fix the colors inside of an image. You just want to modify them. You just want to change the colors in an image.
For example, I am just going to go ahead and close this image and I am not going to save it, which I can do either by clicking on the No button, or you may recall, I can just press the N key here in Windows or the D key for “Don’t save” on the Mac, or you can save your changes if you like, I do not want to limit you.
Now, I have also opened in the background here yellowslats.jpeg. It is inside the Lesson 6 folder, inside the Part 1 folder, and these are actually how the wood slats for our set look before we turn them into wood. We had a yellow background and then we did some wood painting on top of it, some over painting. But it all started with yellow under painting folks.
Little key to our success yellow under painting, but now let us say I do not want the slats to be yellow. I want them to be some other color. Well to Photoshop a photograph, it is just a raw ingredient. That is all that is. You can transform an image into anything you want. And, it changed the colors in this image. I am going to once again take you up to the image menu, choose adjustment where all of the color correction functions hang out. And then choose this little jam right here, hue saturation, which allows you to adjust the hue and saturation values inside the image, which is of course appropriate to change in the color inside the image.
Now, the hue saturation lightness model is another way to measure color. Basically, lightness represents luminosity, so that is sort of independent of color right, the brightness values inside the image, how light or dark they are. Hue and saturation break up what we think of as colors, sort of orange versus purple versus blue and so on.
Hue is the actual colors in the rainbow, these guys right here. This is pretty much by the way that color circle I was telling you about. So, if you are sever part of the circle, lay out that circle in a line, this is what you get. Starting with cyan, going to blue, magenta, red, yellow, green, back to cyan again just like those color options that we saw inside the variations dialog box. So, that is what hue means.
Essentially, just the color by itself free of any considerations about how saturated it is, and in saturation is the intensity of the colors. So, if I move the color saturation down, notice this lower bar right here shows you where the colors are going to go. So, this top bar represents the original colors inside the image, the lower bar represents the new versions of these colors. So, blue is going to change a less saturated blue, sort of a dull blue, magenta to sort of a dull magenta, sort of dull purple color. Orange is going to change to brown, and if you want to make the colors more vivid, you increase the saturation.
And the bars are not so good that it expressing increases in saturation because this top bar already starts super saturated. But you can track the changes to your image in the image window, live and dynamically if the preview check box is turned on as it is by default. So, leave that turn on and let you want to do it before and after comparison. Before with preview off after with preview on, so far, it is a pretty subtle adjustment.
Okay so, what might I really want to do to this image, I am going to crank saturation back down to zero for now, and let me show you some hue modifications. If you do not like the yellow, you want to change it from yellow to some other color, then, you modify the hue. And notice I can just spin these colors around. And again, you can watch these slider bars if you want to, to track how colors are going to remap. Red is going to sort of sharp truce color for example and so on. Or you can just keep your eye on the green slats where are now the green slats here.
So, you make it any color you want to, absolutely any color on earth. If you want them to be red slats for example, we can go for it.
Now, you may need to at this point after you change those hues to different colors
