## Why iglass
macOS's Liquid Glass makes apps feel light and layered. iglass brings that look to your
terminal, carefully:
- **Real Liquid Glass in Ghostty** (macOS 26+): Apple's own glass material, not an imitation.
- **The closest iTerm2 allows**: transparency, blur and a palette designed to sit on top of them.
- **kitty too**: kitty's own blur on macOS (and on Linux desktops that support it), with a title
 bar that's part of the glass.
- **Linux too**: the same palettes in Ghostty and kitty on Linux, with transparency, and blur
 where your desktop provides it.
- **Four glass levels**, mirroring Apple's own options: Clear, Frosted, Tinted and Solid.
- **Follows light and dark mode** automatically, with a separate palette for each.
- **Apple's system colors** and macOS accent colors, adjusted only where contrast requires it.
- **Contrast-checked.** Every color is verified against the window *as it looks over your
 desktop*, not just against a flat background. See the report.
- **High-contrast option** and hints for macOS Reduce Transparency / Increase Contrast (and
 GNOME's high contrast on Linux).
- **Keeps your setup.** Only the look changes: your font, keyboard shortcuts, shell and
 directories stay as they are.
- **Safe and reversible.** Everything iglass changes is backed up and undone exactly on
 uninstall.

## kitty
kitty blurs behind its own windows on macOS, and on Linux where the desktop supports it (KDE
Plasma, Hyprland, niri 26.04+, GNOME 51+). iglass gives it the same palettes, glass levels and accents, a title bar that's
part of the glass, and colors that switch with light and dark mode (kitty 0.38+).
