I am creating a graphic in Photoshop and I've been asked to use a specific Pantone color. Where do I find them?
The Pantone color swatches you speak of can be found in the Color Picker.
In Photoshop CS2...
Click the Foreground color swatch in the tool box
The Color Picker opens.
Click the Color Libraries button.
The Color Picker becomes the Color Libraries.
Select a color library from the Book: dropdown menu
Select a color by clicking on the swatch in the window on the left.
Scroll through all the colors in the library by using the arrow keys.
When you've located the color, click OK.
In previous versions of Photoshop, the color libraries can be found by clicking the Custom button. This may be where your confusion lies. Custom is just too vague. By re-naming the button more accurately, Color Libraries, they have eliminated some confusion.
