What is Pantone 378 C?

Pantone 378 C is a Coated (C) PMS reference in the green family. Its current screen approximation on PantoneTools is #586528, rgb(88, 101, 40), and cmyk(13%, 0%, 60%, 60%). 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 378 C 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 378 C

Green 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. Green shifts differently across CMYK, coated stock, and uncoated stock. For sustainability, food, health, or finance systems, define the approved print and digital variants separately.

  • Use Pantone 378 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 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.
