Blue-leaning

43 colours classified as blue-leaning. The classification comes from the OKLCh hue angle of the manufacturer's published hex, not from an impression: we only claim an undertone when chroma is high enough for it to be real.

Example: Chapeau Violet SW 7136, at chroma 0.0129 and hue angle 266.7°.

What an undertone actually is

An undertone is the faint hue bias sitting inside a near-neutral colour. It is not an impression — it is a measurable angle. We classify every colour by its OKLCh hue angle, a perceptually uniform space where equal numeric steps look like equal visual steps, which HSL does not manage at exactly the low chroma where neutrals live.

We only claim an undertone when chroma is high enough for it to be real. Below 0.012 the honest answer is "effectively neutral", and that is what we say. Between 0.012 and 0.035 the undertone is present but subtle. Above that it is clear.

Why undertone decides the purchase

Two colours at the same LRV can look completely different on the same wall if their undertones pull opposite ways. It is the single most common reason someone paints a whole room and finds their grey "reads purple": the undertone was there all along, but the chip did not say so and the shop's lighting hid it.

Undertone shows itself mostly by comparison and in difficult light. A north-facing room, with indirect cool light all day, exposes it hardest. That is why every colour page on this site shows its nearest neighbours by LRV — undertone becomes visible by comparison, not by description.

How to use this list

Colours are ordered light to dark. Choose first on the LRV the room needs, then use undertone to decide between the candidates that remain. And always order a physical sample: no screen reproduces this faithfully.
