What is color selection?
|
Color selection is the act of picking the color that you want to use in part of your image. At any one time, Photoshop remembers two colors for you: the foreground color and the background color. The foreground color is used when you paint, fill, or stroke selections; the background color is used to make gradients and fill in the erased areas of an image. Some filters also use the foreground and background colors. You can always see which colors are currently selected, since they are shown near the bottom of the toolbox (see the picture, left). The default colors are a white background and a black foreground. |

How
do I
|
There are several ways in Photoshop to change the foreground and background colors; we’ll cover the most common methods here.
|
|||
|
Use the
default colors. Clicking the “set default colors” button
on the toolbox will set the foreground color to black and the background
color to white. (See picture above.) |
 |
||||
|
Swap the
background and foreground. Clicking the small curved arrow on the
toolbox will reverse the foreground and background colors. (See picture
above.) |
 |
||||
|
Use the
Eyedropper tool to sample a color. The Eyedropper tool, located on
the toolbox, lets you simply click on a color in an open image to select
it as the foreground color. To set the background color, hold down the
Alt key when you click. When using a painting tool, you can temporarily
turn the cursor into the Eyedropper tool by holding down the Alt key.
When you let go of the Alt key, the cursor turns back into the previous
painting tool. |
 |
||||
|
Use the Color Picker. To display Adobe’s Color Picker, click on either the foreground or background color in the toolbox. The Color Picker dialog box, shown below, allows you to select a very specific shade, either by visually choosing it or by defining the color numerically. - Visually. The initial white circle is the current color. Drag the little triangles on the vertical color slider to change the range of colors displayed, then click on the desired shade to select it. - Numerically. Enter the correct color code in the RGB, CMYK, HSB, Lab, or Hexadecimal (Web) text boxes. |

When the “Only Web Colors” box is checked in the bottom left-hand corner of the dialog box, Photoshop willl only display colors that will properly display on the World Wide Web: |

When you
are satisfied with your selected color, click the OK button to
return to the image. Note: In addition to using the HSB, RGB, Lab, or CMYK color schemes, you can choose from other color systems, such as Pantone, by clicking the Custom button: |
||||
|
|
|||||
|
Pull down
the Book menu to select the desired color system. Scroll through
the available colors using the color slider on the right, then click on
the color you want. Click OK to return to your image, or click
Picker to return to the Adobe Color Picker dialog box. |
