I used iColorama to colorize a black and white image. Texture applied in a "ghost image" adds interest.
I started with this image that I created previously. You can see how I created it here.
In iColorama, I used Effect/Scrape preset 1 to produce this image. I experimented with all the sliders.
I used Brush/Shatter with a Rough brush at half opacity. Find a brush you like. In Brush/Shatter, as you stroke, you are displacing the image. Your selection of brush as well as the size of the brush will greatly influence the effect. Using half opacity, I allow the original image to show through. This creates the "image shadow" effect: you see both the original and the dispaced image. Then I increased contrast using Adjust/Levels.
I used Preset/Gradient preset 1 with an inverted brush mask to paint color onto her cheeks. When you open your image in Preset/Gradient, you will see a white screen. Tap the Color button at the bottom right of your screen, and your image will appear. Now tap the color picker (white box) in the lower right of your screen, and choose a color. You will see the entire image become tinted with the color you selected. Since I want to apply the color only to the cheeks, I used an inverted brush mask so I could paint the red color only onto the cheeks. You can reopen the color picker to fine tune the color, and you can use the Opacity slider to control the intensity of the effect. I applied, and removed the brush mask.
I again used Preset/Gradient preset 1 in Color mode with an inverted brush mask, this time to paint color onto the lips. I applied, and removed the mask.
I again used Preset/Gradient preset 1 in Color mode with an inverted brush mask, this time to paint color onto the eyelids. I applied, and removed the mask.
I again used Preset/Gradient preset 1 in Color mode with an inverted brush mask, this time to paint color onto parts of the neck and chest. I applied, and removed the mask.
I again used Preset/Gradient preset 1 in Color mode. This time I didn't need a brush mask, instead I selected a slight yellowish color to tint the entire image.
I used Adjust/Exposure and an inverted brush mask, with a very small brush to paint highlights onto her eyelids and mouth.
As a final touch, for emphasis, I used Effect/Raise at low opacity.
