Blue can move from airy, high-lightness tones to very dark values while keeping a recognizable blue hue. The ramp above is computed with fixed HSL lightness steps, so it is a repeatable reference rather than a list of loosely defined color names.
When choosing a blue for a design system, compare the actual HEX values at the contrast level you need. A saturated mid blue may work well as an action color, while lighter shades often need dark text and the darkest shades may support white text.
