The default. Open the laptop on a Sunday morning.
data-theme="light"Light is the theme we open by default because it's the theme most people read all day. The canvas sits at #F7F9FB, a soft blue-grey that's intentionally not pure white. Pure white burns at long sessions; #F7F9FB reads as paper, not screen.
The text picks up #1A2332, deep ink with a navy undertone. Never pure black. Pure black on pure white is the highest-contrast pairing typography offers, but it's also the most fatiguing. Dropping the text 7 percent off pitch and the canvas 3 percent off pure-white together drops the strain without losing readability.
The blue family runs through every surface (canvas, muted surface, border, hover) because Dock's identity color is blue. A neutral grey theme would read as generic SaaS chrome. The blue tint signals tech without sliding into cold corporate.
Long-form work. Drafting docs, reading rows, doing the kind of tasks where the UI should disappear into the work. Default on first install.
Bright daylight or projector demos: the canvas can blow out under direct sun. Reach for Graphite when you need a darker chrome that lets agent colors pop.
