Thistle Purple describes the palest haze, while Prussian Blue gives the nearest ridge enough depth to establish distance.
The color name belongs naturally to distance: atmospheric haze makes a dark ridge appear lighter, quieter, and more lavender than the rock itself.
In a landscape palette, Purple Mountains Majesty belongs in distant forms rather than the foreground. Darker blue-purple layers can advance while this hazier lavender establishes depth.
