#002fa6

International Klein Blue Color
Yves Klein filed a Soleau envelope with France’s INPI on 19 May 1960, date-stamping his ultramarine formula (not quite a patent, more like a claim of paternity). Working with color merchant Édouard Adam, Klein suspended raw pigment in a synthetic Rhône-Poulenc resin called Rhodopas M so the powder kept its full matte intensity. International Klein blue color (#002fa6) still delivers the deep, meditative pull Klein believed opened onto the infinite.

French Sky Blue Color
Clear cornflower blue on a June morning in Provence. French sky blue color (#77b5fe) landed in the xkcd survey list with a name that suits the tone. Trustworthy branding (banks, apps, wellness startups) borrows this open, optimistic blue constantly.
