Colors that go with Bleu Ciel
Charcoal, Crimson and Royal Blue 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 #36454f
neutralshippedCharcoal is the text near-black for Bleu Ciel: softer than #000 and cool enough to feel like part of the same palette.
Crimson #dc143c
split-complementshippedCrimson is a split-complement of Bleu Ciel: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Royal Blue #4169e1
analogousshippedRoyal Blue is Bleu Ciel's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Sienna #a0522d
complementaryshippedSienna sits directly opposite Bleu Ciel on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.

shippedAmber is paired with Bleu Ciel in 8 real palettes, including Lemon Squeezy's brand system and Beach Hut, as the lead colour.
