Orange as a concept didn't arrive in Northern Europe until oranges, the fruit, were imported through (Moorish?) Spain. Chromatically, the space between red and yellow is a lot tighter than the space between yellow and blue. We don't really need a separate color name there, but we have one; it's a distinction that English speakers agree on. If you look at the Munsel color system, one of the first scientific, equidistant color systems, it goes from green, blue, purple, red, yellow, "skipping" orange as a distinct, named color.
