Ok, now we've got our range of colors, all we need to do is apply it. Make the layer of the image you sampled from invisible, we might need it for another color later, but for now it's in the way. Go back to your duplicate layer of the black and white image. To apply the tones, we need a Gradient Map. This changes the tones of an image to match a gradient (hopefully you know what a gradient is). The Gradient Map will automatically adjust the image to the colors in your palette. If the image looks like a negative, check "Reverse" to swap them. We could stop here and have a nice tone, but it's only duotone. What's going to really make our image stand out is adding that third middle tone. Click on the gradient bar and an edit window opens. At the bottom of that window is our gradient. We're going to click in the middle of that gradient to add a point, then change the color of that point to the hex of the mid-tone we captured earlier. Apply that gradient to our image and we've got a good range of tones. But they're not matched to the contrast of our original image. What we need to do now is change the mode of our colored layer to "Overlay" to paste it onto our black and white below. And viola! Our image is colored to our tones. From here, you can Adjust the Hue/Saturation of the toned layer to get a better color (you never pick up just the right colors the first time :)But wait, the whole image is toned!
