The fluorescent orange stripes seen in Tide detergent packaging (and in some highway hazard patterns) do a remarkable thing. They make the yellow stripes look almost dull by comparison.

Nowadays, diagonal hazard panels, like the one shown above, use fluorescent, retro-reflective versions of both colors (the orange and the yellow), but when Tide first went Day-Glo in 1959, it was the orange that was flabbergastingly fluorescent.
In 1959 Proctor and Gamble decided to make a change from conventional to fluorescent color on their Tide detergent carton, using Day-Glo printing inks. Sales of Tide surged, and Day-Glo colors became a standard in product advertising and packaging.
The original Tide box, designed in 1947 by Donald Deskey, used conventional printing inks which were bright, but not fluorescent orange bright.
Tide’s 1959 box was the first package ever printed using the new fluorescent Day-Glo ink
