Notes
Royal Blue is the bright, slightly purple-leaning blue historically associated with British monarchy. The CSS hex carries strong chroma at mid lightness and reads as confident and slightly formal. Editorial, financial, and heritage brands use it as a primary accent. Pair with cream for warmth, or with warm gold for a luxury accent. Against white it passes body text contrast in most sizes and works as a primary action colour or display heading. AA passes at standard body sizes and AAA at 18px and above.
