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.
A tone is the base color with gray mixed in. Tones lose the shout without losing the hue, and they are usually what separates a considered palette from a loud one.

Harmonies are positions on the color wheel rather than matters of taste, which is why they keep working across very different designs.
Two colors from opposite sides of the wheel. They make each other look more vivid, which is why the pairing is used for anything that needs to stand out.
Three neighbors on the wheel. Nothing competes, so the result reads calm and settled, closer to how color behaves in nature.
The base plus the two colors either side of its complement. It keeps most of the contrast while being much easier to balance.
Three colors spaced evenly around the wheel. Strong and lively, and usually best with one dominant color and two accents.
Two complementary pairs, forming a rectangle on the wheel. The richest scheme available, and the hardest to keep from shouting.
One hue at different lightness levels. Effortlessly cohesive, and the safest way to build a palette around a brand color.
Near neighbors, for when this color is almost right. Each one shifts hue, saturation or lightness by a small step.

Whether baby blue works as text, and what to put on top of it when it is the background. Ratios follow WCAG 2.1, where 4.5 is the bar for body text and 3 for large text.
Large text at 24 pixels
Body text at 16 pixels. A flat field of color removes every variable, which is what makes it useful for judging a display.

Used the other way round, #89CFF0 as a background takes #000000 text. That is the higher-contrast of the two, and it is what the tool picks automatically for any chrome sitting on your color.
Baby blue reads better on a black 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.
Marginally more saturated than sky blue and used almost entirely in fashion and nursery contexts. No standard value, so treat this as the common convention.
