Loch Ness

Muted blue-violet anchor, cooler and deeper than Stonewash
About Loch Ness
Loch Ness looks like a deep office-screen purple right after a cool correction: it's saturated enough to hold its own, but it doesn't brighten like Bellflower or Float into softer, rain-lens darkness like Flood. The temperature is more distinctly blue-leaning than the warmer purples in your set, and the undertone reads cooler and a touch heavier, without turning murky.
I use it when I need a secondary state or emphasis that feels serious but controlled. Think product admin consoles, identity and billing flows, and monitoring pages where the UI already has gray scaffolding. It's a good fit for step highlights, table row emphasis, and settings panels that shouldn't feel playful or uncertain, like it's the one you reach for when purple has to behave. Compared to Endless River, Loch Ness is less buoyant and less morning-washed, more anchored.
Pair it with clean off-whites or cool grays. If you drop it on warm creams, it can start to look a bit drained at the edges.
