About selecting colors

You can select colors for your artwork from a variety of tools, panels, and dialog boxes in Illustrator. How you select color depends on the needs of your artwork. For example, if you want to use specific company-approved colors, you’ll want to select colors from the company-approved swatch library. If you want to match your colors with colors in other artwork, you can use the eyedropper or the Color Picker and enter exact color values.

You can use any of the following features for selecting color:

Swatches panel and swatch library panels: Provide individual colors and color groups. You can choose from preexisting swatches and libraries or create your own. You can also import libraries.
Color Picker: Provides a color spectrum from which you can visually select colors, color value text boxes for manually defining colors, and color swatches.
Eyedropper tool: Samples colors from your artwork when you click.
Color panel: Provides a color spectrum, individual color value sliders (such as a Cyan slider), and color value text boxes. You can specify fill and stroke colors from the Color panel. From the Color panel menu, you can create inverse and complementary colors for the current fill or stroke color, and create a swatch from the selected color.
Color Guide panel: Provides several harmony rules to choose from for creating color groups using a base color that you choose. You can create variations of colors using tints and shades, warm and cool colors, or vivid and muted colors. From this panel, you can open a color group in the Edit Colors/Recolor Artwork dialog box.
Edit Colors/Recolor Artwork dialog box: Part of this dialog box provides tools for precisely defining or adjusting the colors in a color group or artwork. The other part lets you recolor your artwork using the colors from a color group, or reduce or convert your colors for output.
Add Selected Colors command or New Color Group button: Create a color group containing the colors in selected artwork. This command and button are both located in the Swatches panel.
