Every swatch belongs to the same family, Blueprint Dark included, so trust, stability, calm run through the palette with nothing to argue against them. Saturation averages 83 percent with Light Blue at the top, which is loud enough that the palette will fight anything else on the page. Prussian Blue and Bright Blue are close enough in hue and lightness that most people will read them as one colour, which makes them a pair to separate rather than two choices to spend.
Blueprint Dark a deep navy or midnight blue, trust deepened into authority and gravity.
Prussian Blue an electric or cobalt blue: trust with real conviction, confident rather than passive.
Bright Blue an electric or cobalt blue: trust with real conviction, confident rather than passive.
Light Blue an electric or cobalt blue: trust with real conviction, confident rather than passive.
Pale Blue a pale sky blue, calm without weight, open, breathable, unguarded.
