Summary

This PR makes a single, very minor color adjustment: --color-error shifts from #FF6467 → #FF6867. The only difference is the green channel increasing by 4 units (100 → 104 out of 255), making the red marginally less saturated. The visual difference is imperceptible in practice.

Findings

1. CLAUDE.md is now out of sync

CLAUDE.md documents the theme colors, and it still lists the old value:

`error` (#FF6467) - Red

This should be updated to #FF6867 to keep the docs accurate. Fix this →

---

2. Rationale is unclear

The PR description says "improved color accuracy and consistency" but doesn't explain:

• Accuracy against what reference? (design spec, Figma file, brand guide?)
• Consistency with which other colors?

A 4-unit green channel tweak is so subtle that without a concrete reference, it's hard to evaluate whether this is the right value or just an arbitrary nudge. If there's a design source of truth, linking it in the PR description would help reviewers.

3. Accessibility — both values pass WCAG AA

Against the dark background (--color-dark: #030712):

Color	Contrast ratio	WCAG AA (4.5:1)	WCAG AAA (7:1)
#FF6467 (old)	~6.76:1	✅ Pass	❌ Fail
#FF6867 (new)	~6.91:1	✅ Pass	❌ Fail

The new value is marginally better for contrast, but neither reaches AAA. This is worth noting in the test plan if strict accessibility compliance is a goal.

---

4. Test plan items are all unchecked

The PR's own test plan was not verified before opening. For a color-only change this is low risk, but it's good practice to at least check the basic items before requesting review.

Verdict

Approve with minor fix — the color change is harmless and the contrast is fine for AA compliance, but CLAUDE.md should be updated to reflect the new value before merging. The rationale could also be strengthened.
