 Red as replacement for orange appeared as early as 1596, but more often after about 1630, as indicated by paintings of that time.It has been suggested that this was due to the orange dye used tending to fade to red over time.It appears that prior to 1664, the red-white-blue tricolour was commonly known as the "Flag of Holland" ("Hollandsche Vlag"); named after one of the revolting provinces.
