What is Pantone 166 C?

Pantone 166 C is a Coated (C) PMS reference in the orange family. Its current screen approximation on PantoneTools is #E35205, rgb(227, 82, 5), and cmyk(0%, 64%, 98%, 11%). Use it when you need a quick Pantone to HEX, Pantone to RGB, or Pantone to CMYK lookup for brand exploration, UI palettes, and print handoff conversations. For accessibility, this page tests Pantone 166 C as a background and currently recommends black text as the safer default before final contrast review. The tints, shades, complementary palette, and developer exports are generated from the same sRGB value so teams can keep web tokens and design notes aligned. These digital values are approximations rather than licensed Pantone specifications; confirm production-critical color with a current physical guide, D50 lighting, and a printer proof.

Workflow context for Pantone 166 C

Orange coated production notes

Because this is a coated-paper reference, use it for glossy stock, laminated labels, premium cartons, and spot-color conversations where ink sits on a less absorbent surface. Do not assume the same visual result on kraft, recycled, or uncoated paper without a separate proof. Orange and warm high-chroma colors are common gamut-risk colors. CMYK fallbacks can lose energy quickly, so compare the process build against a printed proof before replacing a spot ink.

Use Pantone 166 C as a digital reference first, then confirm production work against a physical guide or approved proof.
Record the approved coated value separately from CMYK, HEX, RGB, and design-token fallbacks.
For UI or web use, pair this color with black text only after checking the actual contrast ratio in context.
When sending to a vendor, include the expected substrate, lighting condition, and approval owner instead of only sending a HEX value.

Orange hues are common gamut-risk colors in CMYK because standard process printing has no dedicated orange ink. Use proofing or spot ink for strict brand matches.
