What is Pantone 286 U?

Pantone 286 U is a Uncoated (U) PMS reference in the blue family. Its current screen approximation on PantoneTools is #1F3A93, rgb(31, 58, 147), and cmyk(79%, 61%, 0%, 42%). 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 286 U as a background and currently recommends white 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 286 U

Blue uncoated production notes

Because this is an uncoated-paper reference, use it for absorbent stocks, stationery, uncoated labels, and brand systems where ink will dull or spread compared with coated paper. For glossy packaging or laminated collateral, compare it against the coated companion before approval. Blue brand colors are often stable in digital systems but can darken or purple-shift in print. Keep a clear distinction between spot, CMYK fallback, and UI token values.

  • Use Pantone 286 U as a digital reference first, then confirm production work against a physical guide or approved proof.
  • Record the approved uncoated value separately from CMYK, HEX, RGB, and design-token fallbacks.
  • For UI or web use, pair this color with white 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.
