We already know how to choose a color using the Swatches palette. Unfortunately, the range of choice in it is very narrow. So, what about the other colors? It may be a very simple task if you can find the required color on your picture.

§ 1. Open an image to your choice.

§ 2. From the Toolbox, select the Eyedropper Tool.

§ 3. Find a color on the image that you'd like to paint with and click it with the Eyedropper. Now look at the Foreground Color box (the upper square at the bottom of the Toolbox) - its color has been changed. So, we may activate the Brush Tool and paint with the selected color.

§ 4. While working with the Brush or some other painting tool, you may temporarily activate the Eyedropper by holding down [Alt] key. Once the required color is selected, release the [Alt] key and continue painting.

§ 5. Very often, however, we are not completely satisfied with the colors either presented in the Swatches palette or defined with the Eyedropper. Click on the Foreground Color box to call the Color Picker.

§ 6. Click within the color field to define the most suitable color. If you can't see the required color in the color field, select "H", "S", "B", "R", or some other radio button to change the color field scheme. Then, if necessary, fine-tune the color hue (radio button H), saturation (S), amount of red constituent (R), etc. by moving the vertical slider. There is a number of ways to define a color with this tool; the movie shows only one example. When satisfied, click OK to apply your choice.

§ 7. Similarly, you can customize color in the Color palette. By default, it presents RGB (Red-Green-Blue) sliders. However, you may switch to HSB (Hue-Saturation-Brightness), CMYK (Cyan-Magenta-Yellow-Black), or any other color model available in the palette menu.
