Colors that go with Black Sabbath
Blue Violet, Charcoal and Teal 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.
Blue Violet #8a2be2
analogousshippedBlue Violet is Black Sabbath's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Charcoal #36454f
neutralshippedCharcoal is the text near-black for Black Sabbath: softer than #000 and cool enough to feel like part of the same palette.
Teal #008080
split-complementshippedTeal is a split-complement of Black Sabbath: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Forest Green #228b22
complementaryshippedForest Green sits directly opposite Black Sabbath on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
