Photoshop+Cs3+Setting+Colors

=Working with Colors= With Photoshop, you can alter the appearance of an image by changing the colors that make up the image. Photoshop allows you to work with the //Foreground// color and the //Background// color. These color choices also correspond to the various drawing tools included with Photoshop (e.g., the //Paint Bucket// tool and //Brush// tool).

Selecting Colors
You can move between two color options at a time, the //Foreground// and //Background// colors. The //Background// and //Foreground// colors are used differently by each tool. For example, the //Brush// tool uses whatever color is in the //Foreground// box. The //Background// and //Foreground// colors can be switched at any time.

The Color Picker Dialog Box
The //Color Picker// dialog box allows you four options to set the color: the color field, the color slider, numeric values, and hexadecimal values. The //Color Picker// opens when you go to select a color using the //Toolbox// Four groups of text boxes appear:
 * ~ Option  ||~  Definition  ||
 * **Color Field** || Identify which color will be added by moving a small circle which appears in the //Color Field//. ||
 * **Color Slider** || Change the color tone by moving the arrows along the bar or by clicking inside the //Color Slider//. ||
 * **Numeric Values** || Select a color by typing the numeric value in the group of text boxes.
 * 1) //HSB// (hue, saturation, brightness)
 * 2) //RGB// (red, green, blue)
 * 3) //Lab// (lightness, green-red axis, blue-yellow axis)
 * 4) //CMYK// (cyan, magenta, yellow, black) ||
 * **Hexadecimal Values** || Enter a six digit hexadecimal value representing the color you want. ||

Using the Color Picker Dialog Box
HINT: The //Toolbox// is located at the left hand side of the work area by default. If the //Toolbox// is not visible, re-select it in the //View// menu.

Recoloring Graphics
Photoshop allows you to recolor images. For example, if you wish to change the color scheme of a document, you can recolor related images in Photoshop. The active //Foreground// or //Background// color can be applied to any selected area of the image. For information on how to select an area, refer to Selecting an Area.

Recoloring Graphics: Using the Fill Command
One way to change the color of an image is by using the //Fill// command. The //Fill// dialog box allows you to fill with either the //Foreground// or //Background// color, or with black, white, or gray.

NOTE: The //Paint Bucket// command will not work on a bitmap image. If this tool is not available, check your image mode.
