Dusty, slightly warmer periwinkle for subdued panels
About Old World
On my monitor, Old World reads like a softened periwinkle leaning slightly toward lavender, the way a painted wall looks after daylight hits it through blinds. It's calmer than Azureno, less "blue-push" than Birdie Num Num, and it doesn't go as misty and controlled as Mont Blanc. The saturation is restrained, but not washed out, so you still feel the color under the surface.
I use Old World as that primary-ish purple-blue for quiet hierarchy: section headers, tag pills, and link states in product interfaces and dashboard designs where you need clarity without the sharper cool. Compared with the neighboring purples, it lands between their personalities. It's cooler than Birdie Num Num, but it doesn't carry the clinical edge Azureno can have. In dashboards and finance apps, it helps buttons and metrics feel organized rather than intense.
Pair it carefully with warm creams. If you go too beige, it can start to look flatter and more gray-lavender than you intended.
