#1978b3rgb(25, 120, 179)hsl(203, 75%, 40%)oklch(0.55 0.123 242.7)Charcoal, Rust and Sienna lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Charcoal is the text near-black for #1978b3: softer than #000 and cool enough to feel like part of the same palette.
Rust is a split-complement of #1978b3: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sienna sits directly opposite #1978b3 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Amber is paired with #1978b3 in 9 real palettes, including Lemon Squeezy's brand system and Wired's brand system, as the lead colour.
12 real palettes, including Activision's brand system and Pixar's brand system put Blue beside #1978b3, as the accent.
Designers have shipped Cobalt Blue with #1978b3: 8 real palettes, including Glacier and Hershey's's brand system, as the accent.
Crimson is paired with #1978b3 in 15 real palettes, including NASCAR's brand system and Wendy's's brand system, as the supporting colour.
