Looking at Artwork, Imagery, and Color

An image in Photoshop is color. Whether the image is in bright, vivid colors, various shades of gray, or even just black and white, it doesn't exist without color. At its heart, Photoshop is about assigning the correct color to each pixel.

Choosing Colors from the Color Picker

The toolbox contains buttons to set foreground and background colors. You can click the Set Foreground Color or Set Background Color button to open the Color Picker. The Color Picker shows you the spectrum of colors to choose from. The first time you use Photoshop CS2, the default state of the Color Picker displays the slider and field using the HSB color model, designated by the radio button. You can move the vertical color slider to choose a hue. Then in the large color field, you can click to change the saturation and brightness level of that hue. When you click a color, the values change in the HSB, RGB, Lab, and CMYK fields, and so does the RGB hexadecimal value (next to the # sign).
