Origin of Navy and Royal Blue

Navy

Navy blue was standardized as the British Royal Navy officer uniform color in 1748 and quickly became the global shorthand for naval and later police/military authority. The word 'navy' as a color name first appears in English in 1813.

Royal Blue

Royal Blue reportedly originated in early 1800s England when millers in Rode, Somerset entered a competition to create a new blue dress fabric for Queen Charlotte. The exact winning shade has drifted over two centuries but the name stuck.

▣Interior design & walls
PickRoyal Blue

Royal Blue is the more muted of the two (73% saturation) and sits more calmly on large wall surfaces, while Navy's higher chroma can overwhelm a room when used beyond accent pieces.
