About Seaside

Seaside feels like morning light sitting on the surface of calm water. It's notably lighter than , but it doesn't go as airy as , so it holds a steady presence without turning washed out. Compared to , it's less warm and less cyan-forward, with a cooler, sea-glass undertone that reads clean rather than friendly-coral warm.

I use it when I need that in-between balance for buttons, card headers, and subtle surface fills in dashboards and finance apps. It works well as a secondary UI color in SaaS and health platforms where you want calm reinforcement, not a strong accent. It's also a nice fit for chart backgrounds and annotation pills in light layouts, because it stays legible and doesn't steal focus.

Quirk to watch: on very cool monitors it can lean a touch more gray-blue, so pair it with grays that aren't already too blue or everything starts to feel samey. The upside is that it's the shade I reach for when the layout needs consistent, seaworthy calm across multiple components.
