Changing Colors with Hue/Saturation
Now we're going to look at how we can change the color of an object also using an adjustment layer okay, so this corbett did not use to be pink it started its life as a nice shade of teal ok, so let's take a look at how I did this let's look at the layers panel so we've got an adjustment layer going on we know that it's an adjustment later because it's got that little slider and we've got a mask that's telling us whatever is happening on this adjustment layers only being revealed where there is white and that just happens to be the shape of the car case let's take a look at how to create this we're gonna go ahead and leave that layer hanging out in this time we're going to start out with a selection okay? So kind of like we did in the curves adjustment where we created a selection and then we added the adjustment layer that way photoshopped feels in the mask for you so the easiest way to create a selection of this car is with one of our selection tools that work on color because we nee...
d t to select the turquoise in order to change it so we're going to go ahead and use the quick selection tool and I'm going to go down and brush size a little bit and click and drag to paint across my car when I get into areas that are smaller than I need to go down and brush size because remember the size of the area that's being grabbed by this tool is directly dependent or proportionate to you rather the size of the brush cursor, so if you want to grab a really small areas and you need a really small brush now, this is also a great opportunity if you can't get this selection perfect with the quick selection tool it's a great opportunity to pop in and out a quick mask to find tune it, but the quick select control, at least with this particular image, we'll give you a good selection of this car taste, and once you've got a selection of the car, then we're going to go down to the half black, half white circle, the bottom of the layers panel and this time we're going to choose hugh saturation and a panel open if you're in cs four c s five here in any earlier version, the dialog box will open with the same set of sliders. What you want to do here is grab the hugh slider and twirl her around one a red corvette new problem, and then we've got a red corvette, so as you drag the huge slider, you're changing the color of what it used to be to whatever color your landing on in the hues, slider see if I stop in the green section c here I'm in the in the greens and I've got a green car pretty amazing her as long as you can get a selection of it, you can change that baby to anything you want, provided there is color on it now changing black to another color is a completely different affair that is beyond the scope of this here class same thing with white you really need to have color to be able to change it well, not saying it can't be done, it cannot be then is easily is this ok? So let's say that you want a purple corbett, but you don't want it quite that bright of a shade of purple. Well, then you can experiment with the saturation slider, which will make the color less vibrant if you drag it to the left, see how it's making in a little less bright. Okay, so saturation is kind of like the vibrancy of the paint, so if you want a super bright, you drag it to the right. If you want that purple to be lighter or darker, then you can experiment with the lightness slider so I can drag it to the right for a little bit lighter I can drag it to the left to make it a little bit darker, so that's a fabulous way to add color to an image, so let me see what other images I've got here let's do this again on another image, so our scheer later her skier lady right here did not used to have a purple jacket on used to be really, really bright red, so we're going to use thie exact same technique to change that. So I'm gonna go ahead and create a selection of her jacket, the area that I want to change, and if you're dealing with an image that has less contrast than this, then you'll have to work a little bit harder at it, but you can still do it. I'm gonna zoom in, use my space bar to go over to this part of the image just to make sure that I'm catching that whole sleeve and notice how small I've made my brush cursor, ok, it's really, really little because I'm trying to select a really, really small area, and I don't want that tool to go hog wild to start graham and a whole bunch of pixels that have nothing to do with the color I'm trying to actually change to come up here, dip into her collar and again, if you cannot get the selection perfect with this tool, great opportunity to pop in and quick mask mood, so I'll do that right now, too. Subtract this part from the selection and add this part so I pop into quick mass mode by pressing q so now I'll switch to the regular breast tool and painting with white well actually subtract from my selection so hopefully with these examples you're starting to see how you can use many tools in conjunction with each other teo achieve a desired effect ok so start out with a quick selection tool why? Because it's so darn fast don't worry too much if you can't get a perfect selection with it know in your heart of hearts that you can always pop into quick mask mode in hand feinting that selection by painting with black toe add to this election or painting with white to subtract from the selection but you do want to switch to the regular brush tool to do that now when we come back to our image here we pop out of quick mass mood now I can see my marching is and I've got a perfect selection of her coat so I can do the exact same thing again I could go down to the half black half white circle the bottom of the layers panel choose hugh saturation player l with my hugh slider if I would like maybe she would like a green coat now I am seeing a little bit of the red pixels left over anybody know of a trick we can use to fix that oh, maybe a certain filter that might weidner mask open our mask up a little bit, so with the mask active, we're going to go up to the filter menu into other member have when we were changing the background of the guy with the cowboy hat on the green background and the blue bonnets and we used a minimum to tighten the mask a little bit, we can use maximum open if the mask a little bit so we can come up here to maximum and probably about one pixel would do it so there's a before and there's after you might have to use one point five to get it, get rid of that halo so it won't let you do one point five so only whole numbers in that dialogue so that's how you can quickly change the color of the image. You can also experiment with the cull arise checkbox if you turn that on your colors, we're going to shift pretty dramatically and then you're going to have to go back to the huge slider it play around again. Your colors will become more muted by turning on colorize it just changes the way the color on the adjustment layer is interacting with the color that's on the original layer, so you'll get a little bit of different results when you use that yes, right below her chin is a red hue shadow cast how would how could he change that as well too on her face yeah, that that you're going to have to do a little bit of manipulation on you could go in with the um josh when you could select that area of her face and then just reduce the red that's it meant one spot you could try that or you could try using the dodge tool toe light in that area just a little bit to fix that so that that is a challenge with this one image because her her original jacket was so bright that it's actually reflecting on her face just a little bit yeah when I learned to do the change color technique it was tio make a separate layer and paint and then change that layer style the color you could probably use that to change the color under her chin just to picking up her skin tone color yeah, you could do that so this is just one way to change the color of anything. Okay, so the way we've been looking at so far is creating a selection of the offending color if you will and then adding a huge saturation adjustment layer in dragging the hugh slider to get the color that you want so let's look at another way to do that and again it's six in one hand half dozen in the other which ever way works better for you
