In the Pantone Color Guide, what does the "C" in color 150c refer to?

The "C" in Pantone color 150c refers to "Coated," indicating that this particular color is designed for printing on coated paper. Coated paper has a smooth finish that enhances the vibrancy and richness of colors, making them appear more saturated and bright. This designation is crucial for graphic design and printing, as colors can look significantly different on coated versus uncoated paper.

In contrast, uncoated papers would have their corresponding Pantone colors designated with a "U," reflecting the different finishing effects that paper types have on ink. Understanding this system helps designers choose the right color accurately for their intended media, ensuring the final printed product meets their expectations.
