| Colorizing Images Often, we want to make a black and white image colored. Sometimes the purpose is to make it look as if the greyscale image were originally shot in color, as with the Turner Classic Movies on TV. However, often the goal of colorization is to radically change the look and feel of an image. There are two major techniques that are useful for colorizing. On photographic greyscale images, an overpainting technique is useful. Use the original greyscale image as your background. Make sure that you've changed the color mode on the image to RGB color. The background layer will still appear in greyscale. Then, simply paint over the greyscale image on new layers with varying opacity. Also try fiddling with the layer modes to get the proper kind of overlay.
The other technique to use when coloring images is the over/underpainting technique. This technique works best on black and white line drawings, often found in clipart or when you scan in a sketch you've done. First, color the image as you would with the overpainting technique, making new layers above the line drawing. Once you've got the image colored in, move the line drawing to the top layer. Using the blending slider in the layer properties dialogue box, you can automatically make the white parts of the layer transparent, allowing your coloring to show through while keeping the black lines strong. Once you've got your image the way you want it, try flattening it and then running the posterize filter to bring everything together.
