Color schemes built on prussian 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 neighbors on the wheel. Nothing competes, so the result reads calm and settled, closer to how color 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, #003153 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.
Prussian 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.
