Image colorization tutorial

In this tutorial we are about to learn How to colorize a black and white image.

The underlying features that we will explore in this session are layer sets, layer modes, and selection sets.

Let’s take a look at our source image. As you can see, it is a B&W image of a young woman. (I found it on a public website...)

Step first: Change the Image mode of the image
First things first. Rename the background layer to source and create a duplicate layer of the source. Now we’re ready to begin.
When we opens any B&W image in photoshop, it's mode automatically sets to grayscale. Change mode to RGB (As we are going to colorize this image). Change the mode by selecting Image > mode > RGB.

Step Two: Create new Layer set
Photoshop has an amazing layer management tool known as the “layer set.” Basically this is a folder system that allows us to place a group of layers underneath a main folder that can be opened or closed at will. This feature is perfect for what we need to do.
Let’s add a layer set. At the bottom of the layers palette is an icon that looks like a folder. Left-click on this icon and a gray layer will be added to the layers palette that says “Set 1”. Right click on the Set 1 layer, select “Layer Set Properties” and rename the layer set to “Colors”.

Step Three: Create 'color mode' blended layers
Now we need a new layer in the colors layers set. Add a new layer from the bottom of the layers palette. Rename this layer to 'face' because We are now going to colorize her face. This naming convention is the preferred organizational method to use when working with colors in a B&W image.

Now we begin the process of colorizing our layers. Select the 'face' layer and begin to paint onto the parts of the face and her body with the color of face(You can pickup color from another sample image by eyedropper tool). Notice that you can’t see through to the source image below. This is due to the fact that you are in NORMAL mode for this layer.

When colorizing an image, there are two modes that you will primarily want to use. These modes are COLOR and OVERLAY. The primary difference between these two modes is that OVERLAY blends the color you are painting with into the colors on the layers below the one you are working on. What this means is this particular case is that the 'face' color is blending with the grayscale colors below it. While not necessarily bad, it tends to wash out the color range. COLOR mode however, maintains its “adjacent” properties and blends itself by taking the grayscale color below it and applying a “monochromatic” blend. This effect produces a much more believable color range.

Without cleaning up your color, change the layer mode to “Color” and adjust the opacity to as you wish. Now we can see the areas that we need to clean up. Using the eraser tool and a soft brush, clean up your 'face' color lips.

Now add a touch of color to the lady’s cheeks and lips. You are very clever, noticed that one another layer with the color mode added for colorize lady's lips. Yes, it is. We can use multiple layers for colorize different parts of an image.

Step Four: Colorize all the parts of the image.
Now you have good knowledge of the image colorization and how to use layer sets, layers and image modes.
Now you can try your B&W image for colorization. Look below for the final colorized image.

You’re now ready to go out and colorize the town red!
