Zeraphim
A turquoise-and-teal theme in light and dark, built from the Faceted Clarity design system behind jcdiamante.com. Full syntax, UI and 24-colour terminal coverage, with contrast-corrected shades so the light variant stays legible on paper-white.

Turquoise and teal. Light and dark. Same palette, everywhere I work.
Most themes give you somebody else's colors. This one is the palette from my own site — the "Faceted Clarity" design system behind jcdiamante.com — turned into an editor theme.
Deep navy canvas, turquoise accents, and a genuinely usable light variant that
isn't just the dark one with the lightness flipped. Every color role was
re-derived for a paper-white background instead of being reused, because a
turquoise that sings on #060a13 is illegible on #ffffff.

What's in the box
- Both appearances, at full parity — 152 style keys each, no gaps between the variants
- 45 syntax captures, covering everything Zed's built-in One theme styles,
including
emphasis.strong,punctuation.list_markerandstring.special.symbol - 24 terminal colors — all 16 ANSI slots plus bright and dim variants, so the integrated terminal matches the editor instead of fighting it
- 8 player colors for collaboration cursors, drawn from the brand hues
- Italic comments, bold-italic keywords, and weighted headings, echoing the Syne/Lexend split on the site
- Contrast-checked — every foreground was measured against the surface it actually lands on, not eyeballed
About the light variant
Three brand colors don't survive a white background. #c88813 amber reaches
only 2.6:1 as text, so warnings, numbers and constants use a corrected #8f6410
while the original amber stays for decoration. Same story for the faint inks.
The dark variant uses the brand tokens verbatim.
The terminal's white slots are deliberately inverted in the light theme — programs assume ANSI 15 is a legible foreground, and literal white vanishes on paper.
