Now, Photoshop offers one more tool that allows you to recolor portions of an image and this tool replaces one group of colors with a different group of colors. Let me show you how it works. Go and click and hold on the brush tool icon to display a fly out menu of alternates and choose the final alternate, the color replacement tool and I am going to zoom out inside of this image here.
Now, let us say instead of replacing the red eye for example, because this tool can replace red eye inside of an image, let us say I want to replace some other area of color. Let us start by replacing the color of Sammy’s shirt over here. I am going to do that by increasing the brush size for starters.
So, I will click on the brush around that down pointing arrow either way and I am going to go ahead and increase the brush diameter. Notice that the palette looks little different when you are using this tool. For what it is worth, you do not have that list of predefined brushes. I do not know why, it is just Photoshop playing games with you. So, I will go ahead and raise this diameter value.
This is something pretty big. Actually, 104, something like that. That is probably pretty good and now, we have a bigger brush and I am also going to select a different color. Let us select something that is pretty radically different. I will just go ahead and choose Swatches from the Window menu and I am going to select the green, something that is pretty different than any of the colors going on inside this image right now.
Now, I am going to paint inside of Sammy’s shirt, and as long as you keep that cross, that little plus sign that is at the center of the brush cursor, as long as you keep it inside Sammy’s shirt, you should be good to go. You can even extend the brush out. Notice that the circle of the brush is going into his arm but as long as you get the plus sign in there, you are just fine. This is working out nicely. Actually, pretty cool tool.
Now, every once in a while, we will screw up like that and if you move the plus sign into the other region, now then you are really in trouble. Okay, so I am going to go ahead and undo.
Now, the big problem is that once I made a mistake with this brush, I had to undo the whole thing, did I not? I could not undo just a little bit of that brush and that is why I recommend. If you are going to use this tool to just sort of drag little areas. Just make sort of small adjustments at a time. In that way, if you do end up making a big mess of things like so, you can undo just that little brush stroke you will apply. Okay, so I will just keep brushing inside this.
Now, there are a bunch of different options available up here inside the options bar. For example, by default, the mode is set to color, that is a good thing if we want to recolor elements inside the image. But I do want to demonstrate these two options right here, sampling and limits. Both of which are extremely useful. Sampling decides what colors you are going to replace and by default, it is set to continuous and that means that as you drag, the brush is constantly reading the color that is directly underneath that plus sign. So, it is finding that color and it is replacing it with the foreground color that you selected. So, it is constantly updating on the march and that means if you drag from here to here, it goes from deciding to replace green with green to deciding to replace red with green.
If you do not want that to happen, if you want to give yourself a little more room to be sloppy, what have you? Then you can change the sampling option to just sample once. You can also change at the background swatch, just that means, whatever the background color is which is white right now, that is all it is going to replace. Not very useful. Better I think is once. That way, it evaluates the color and replaces it on the fly.
So, for example, let me work inside the couch here. I will go ahead and select in orange from the swatches palette. So, I will change my foreground color here on the toolbox to orange and then I will drag inside of the couch. And now
