About royal blue
A CSS keyword, and brighter than most people picture. The name traces to a British competition to make a blue for the queen, which is a better origin story than most colors get.
Shades, tints and tones

Shades of royal blue
A shade is the base color with black mixed in. Shades read as deeper and more dramatic, and they are what you reach for when a color needs to recede or carry weight.

A tint is the base color with white mixed in. Tints turn pastel as they lighten, which makes them useful for backgrounds and for anything that has to sit behind text.
Tones of royal blue

Color schemes built on royal blue
Harmonies are positions on the color wheel rather than matters of taste, which is why they keep working across very different designs.
Analogous
Three neighbours on the wheel. Nothing competes, so the result reads calm and settled, closer to how colour behaves in nature.
Split complementary
The base plus the two colors either side of its complement. It keeps most of the contrast while being much easier to balance.
Triadic
Three colors spaced evenly around the wheel. Strong and lively, and usually best with one dominant color and two accents.
Tetradic
Two complementary pairs, forming a rectangle on the wheel. The richest scheme available, and the hardest to keep from shouting.
Monochromatic
One hue at different lightness levels. Effortlessly cohesive, and the safest way to build a palette around a brand color.

Used the other way round, #4169E1 as a background takes #FFFFFF text. That is the higher-contrast of the two, and it is what the tool picks automatically for any chrome sitting on your color.
Royal blue reads better on a white background of the two. Contrast is a property of the pair, not of one color, so a color that fails here can still be perfectly usable against a different partner.
