Royal blue
Royal blue (French: bleu roi , bleu de roy or bleu royal ) refers to any deep blue color, especially a blue that goes red , also certain tints of cobalt blue ( smalt ), Berlin blue (also Prussian blue, Parisian blue) or even indigo .
The name comes from the blue uniforms and liveries that the body guards and court officials of the French kings wore since Louis XIV .
The fabric dyers first treated their fabrics with orseille (for purple coloring ) or cochineal (carmine) and then put them in the blue dyeing tub.
