How do you determine which number you have in the PANTONE color chart? There are so many libraries. For example, I have the following color from the PANTONE solid coated library in Photoshop 7473 C. But, I can't match this up on the PANTONE color chart (outside of "eyeing" it). Is there some sort of cross-referencing technique for these libraries?
The Pantone color library collection has grown considerably in the past few versions. If you have been given a specific Pantone color you should stick with it. If you're interested in recreating the color you can break the color down into its individual parts.
Double click the Background color swatch to open the Color Picker.
The Color Picker opens.
Click the Color Libraries button.
The Color Libraries dialog box opens.
Select Pantone Solid Coated from the Book: dropdown menu.
Type the numbers 7433 to jump to the color. There are no text entry boxes, just type.
Click OK. The background color swatch is changed to Pantone 7433C.
Open a new document.
Choose File > New (any size will do)
The New dialog box appears.
Select Background Color from the Background Contents: dropdown.
A new doc opens with the new color in the background.
Now we'll analyze the color.
Choose Window > Info
The Info palette opens.
Select the Eyedropper tool
Position the Eyedropper tool over the color background.
Look in the Info window, the color is broken down into three RGB values as well as four CMYK values.
Make a note of these numbers.
Now when you need to reproduce the color, just enter the values in the appropriate text entry box in the Color Picker.
I hope this helps.
