#cdefe9rgb(205, 239, 233)hsl(169, 52%, 87%)oklch(0.926 0.036 183.7)Charcoal, Lilac and Plum 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 #cdefe9: softer than #000 and cool enough to feel like part of the same palette.
Lilac sits directly opposite #cdefe9 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Plum is a split-complement of #cdefe9: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sand completes a triad with #cdefe9 — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Sky Blue is #cdefe9's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Amber is paired with #cdefe9 in 21 real palettes, including Blueprint and Trailhead, as the accent.
47 real palettes, including Dropbox's brand system and Alaska Airlines's brand system put Blue beside #cdefe9, as the accent.
Blue Violet is paired with #cdefe9 in 12 real palettes, including Gemstone and ClickUp's brand system, as the supporting colour.
