Specifically, Contrast Deep Blue has a lightness of 20% and a saturation of 100%, steady and powerful as a background or primary color, pairing well with light text for good readability; moreover, its saturation is extremely high and its visual tension is strong, so it works best used sparingly as a focal accent. In a word: Paired with yellow, as in the aircraft of Nausicaä of the Valley of the Wind, to add depth to the scene.

For this reason Contrast Deep Blue tends to leave a first impression of being cool and reliable in the viewer’s mind, and this emotional tone also defines the role it plays in design.

In real projects, Contrast Deep Blue is also often used as a dark background or heading text color; in “Blue”-themed designs, the adjacent colors or lightness gradients built around it quickly establish a cohesive, clearly layered color scheme.
