Pantone has a perfect cross-reference tool on their website that can be found here. This cross-reference tool is between one Pantone book and another Pantone book. We have found that the color may not be the same even when cross-referencing one Pantone number to another. For example, a cross-referenced color in the Fashion Home & Interiors Guide to the Formula Guide may not be 100% the same. For this reason, if you need to match a color exactly from Pantone, you should have the exact color chip from the exact Pantone guidebook and use that to match the color.
