// Solarized skin
// ==============
// Created by Sander Voerman <mailto:sander@savoerman.nl> using the Solarized
// color scheme by Ethan Schoonover <https://ethanschoonover.com/solarized>.

// This style sheet implements three options for the minima.skin setting:
// "solarized-light" for light mode, "solarized-dark" for dark mode, and
// "solarized" for light or dark mode depending on user preference.

// Color scheme
// ------------
// The inline comments show the canonical L*a*b values for each color.
//
// Some colors were altered from the canonical scheme to comply with
// WCAG-contrast criteria between foreground and background colors.
