alpha
Perceptually balanced isoluminant syntax palette with a restrained interface. Two variants — alpha dark and alpha light.
Two variants
Same seven hues. The dark variant locks lightness; the light variant retunes it to keep weight equal on white.
Designed for legibility
A handful of design rules, applied consistently across the whole theme.
Two variants
alpha dark and alpha light. A clean, familiar surface in both — switch with the OS, or pin one.
Isoluminant palette
Dark variant locks every syntax color at HSL(h, 100%, 68%). Only the hue rotates, so no token visually outweighs another.
WCAG-AA in light
Light variant retunes lightness per hue to clear ≥ 4.5:1 contrast on white. Saturation stays at 100%, weight stays equal.
Restrained chrome
Editor, sidebar, status bar, tabs, panels, terminal, and git decorations are tuned to stay quiet, so the code can speak.

Seven hues, equal weight
