Technical Profile

What color is Sudden Sapphire? It's a medium warm blue with the hex code #4F76E7. Sudden Sapphire is a distinctive shade in the Behr lineup, and while close cross-brand equivalents exist, its specific blend of warm tone and medium depth gives it a character worth comparing in person. Sudden Sapphire has a warm (pink) undertone, which affects how it pairs with trim, flooring, and adjacent wall colors. Understanding a color's undertone is key to avoiding combinations that clash — it often matters more than the surface color itself.

Its warm (pink) undertone means trim and ceiling whites should lean neutral to avoid a jarring clash.
