Using The Color Picker

Hello,
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 will 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.

Pull down the Book menu to select the desired color system. Scroll though the available colors using the color slider on the right, then click on the color you want. Click OK to return to you image, or click Picker to return to the Adobe Color Picker dialog box.

Thanks For Reading!!!!
Hope you will be back for more updates on Photoshop!!
