#22c55ergb(34, 197, 94)hsl(142, 71%, 45%)oklch(0.723 0.192 149.6)Obsidian Accent on this page is the real value, not a screenshot: exact hex, RGB, HSL and OKLCH, ten tints and ten shades, classic harmonies, and WCAG contrast with fixes — plus the 2 public brands that use it and the palettes it appears in.
Charcoal, Blue and Royal Blue lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Charcoal is the body-text near-black for Obsidian Accent: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
4 real palettes, including Spotify's brand system and Minecraft's brand system put Blue beside Obsidian Accent, as the accent.
Royal Blue is paired with Obsidian Accent in 6 real palettes, including Brilliant's brand system and Docker's brand system, as the accent.
Taupe is paired with Obsidian Accent in 9 real palettes, including Obsidian's brand system and Chime's brand system, as the text colour against it.
Fuchsia sits directly opposite Obsidian Accent on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Hot Pink is a split-complement of Obsidian Accent: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Cornflower Blue completes a triad with Obsidian Accent — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Dark Olive Green shows up next to Obsidian Accent in 3 real palettes, including Undergrowth and 7-Eleven's brand system, as the supporting colour.
| Obsidian Accent as text | Ratio | AA | AA large | AAA | Fix |
|---|---|---|---|---|---|
Aaon white | 2.28:1 | fail | fail | fail | |
Aaon black | 9.22:1 | pass | pass | pass | Passes AAA — no fix needed. |
Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with Obsidian Accent as the background.

Every direction it proposes comes with a /colors/d/… link: open it, lock what you like, paste the link back, and the agent edits rather than re-rolls.
