A. Select by Color Range

Sometimes you can simplify a very complex selection by not trying to select the various parts individually, but rather by selecting them by their color. For example, I want to turn the warrior green instead of gray in the file Warrior.jpg.

  1. Open the file Warrior.jpg (High School\ Shared\ Graphics\ Lessons\ Selections). 
  2. If I try to select the warrior with one of current methods (magic wand, masks, etc.) it may take a while. We have another method specifically for these types of selections.
  3. Make sure everything is deselected before continuing, Select-- Deselect.

1. Open Warrior.jpg

  1. Open the Select by Color Range window
    1. Select-- Color Range. The Color Range window should appear with an all black screen.
    2. Using grayscale colors (black, white and grays), this window shows you what are you are selecting.
    3. Black means the area is not selected.
    4. White means the area is selected.
    5. Gray means the area is partially selected.

4. The initial Select by Color Range window.
  1. Roughly Select the Warrior.
    1. Move the Color Range window to the side.
    2. Using the eyedropper that appears, click on a gray color in the warrior in the image screen.
    3. You should see a figure of the warrior appear in white in the Color Range Window.
  2. Perfect the Selection.
    1. In the Color Range Window, slide the Fuzziness bar over until the entire warrior area is white, but none of the background is turning gray.
    2. If I slide the fuzziness all of the way up, I may end up selecting some of the background as well. I don't want to do this.
    3. If I slide the fuzziness bar all the way down, I may not select enough of the warrior.
    4. Press OK when the selection is complete.

5 & 6. After adjusting the fuzziness (I used a setting of 130), the warrior is selected.
  1. Create a new layer to put the color into, Layer-- New-- Layer. Make sure you are working in the new layer. We don't want to touch our original image.
  2. Fill the area with Green.
    1. Choose a green for the foreground color.
    2. Edit-- Fill
      1. Use: Foreground Color
      2. Mode: Normal
      3. Opacity: 100%
  3. You should now have a green warrior.

8. Fill the selected area in a new layer with green.

Selecting by color range is often a quick way to select very complex areas.
