Colors that go with #addaf5
Charcoal, Goldenrod and Sandy Brown 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 #addaf5: softer than #000 and cool enough to feel like part of the same palette.
Goldenrod #daa520
split-complementshippedGoldenrod is a split-complement of #addaf5: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sandy Brown #f4a460
complementaryshippedSandy Brown sits directly opposite #addaf5 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
