If you use Pantone colours with your Adobe software, you'll need to pay a monthly fee. Pantone is putting its 15,000 colours behind a paywall starting this month. The only Pantone Color books that remain free to use are Pantone + CMYK Coated, Pantone + CMYK Uncoated, and Pantone + Metallic Coated. Pantone passes the cost to users through the Pantone Connect plug-in for either US$59.99 per year or US$7.99 a month.
