Description of Changes

Summary by CodeRabbit

  • 개선 사항
    • 툴팁과 토스트의 색상 대비와 가독성을 개선했습니다.
    • 어두운 배경과 밝은 전경색을 적용해 다양한 테마에서 시각적 일관성을 높였습니다.
    • 정보성 토스트와 툴팁에 개선된 반전 색상 스타일을 지원합니다.

배경

  • Tooltip 배경은 background.contrast-200 사용
  • Dark 모드에서 canvas 대비 부족 → WCAG 2.1 SC 1.4.11 (Non-text Contrast, 3:1) 미달
  • Border(border.normal)가 tooltip 배경과 동일 색상 → 경계 무력
  • Shadow(shadow.md, black@20%)는 Dark 캔버스 위에서 3:1 대체 불가

접근성 진단 (변경 전)

대비 쌍 Light Dark 판정
tooltip bg ↔ canvas-base 11.55 : 1 2.50 : 1 Dark ❌
border ↔ canvas-base 1.31 : 1 2.50 : 1 참고
border ↔ tooltip bg 8.83 : 1 1.00 : 1 Dark ❌ (동색)

변경 사항

  • canvas-inverse 토큰 신설 (canvas 그룹에 추가)
  • Tooltip, Toast 배경을 신규 토큰으로 교체

토큰 값

토큰 Light Dark
canvas-base #ffffff #232323
canvas-inverse (신규) #393939 #dcdcdc

접근성 검증 (변경 후)

대비 쌍 Light Dark 기준
tooltip bg ↔ canvas-base 11.55 : 1 11.46 : 1 ≥ 3:1 ✅
tooltip text ↔ tooltip bg 11.55 : 1 11.46 : 1 ≥ 4.5:1 ✅
  • Dark 모드 SC 1.4.11 위반 해소
  • Text 대비도 SC 1.4.3 (4.5:1) 충족

명명 근거

canvas-inverse — 산업 표준 다수 시스템의 관용어 채택.

Tooltip은 canvas-inverse 배경과 foreground.inverse 전경색을 사용합니다. Toast의 info 팔레트도 같은 토큰을 사용합니다. danger와 success 팔레트에는 흰색 전경색을 적용합니다. 제목과 설명은 색상을 상속합니다. Minor 릴리스 changeset을 추가했습니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 3e3dc

The change improves tooltip and toast contrast, but the current implementation still renders the dark inverse canvas with the wrong shade and leaves danger/success toast descriptions below the required text contrast threshold. These localized accessibility and visual-correctness issues should be fixed before merging.

다크 테마의 dangersuccess 토스트에 foreground.inverse를 사용해야 합니다.

다크 테마에서 배경은 각각 #f14f5a#259a77입니다. 현재 foreground.staticWhite를 사용하면 대비가 약 3.5:1입니다. description은 일반 본문 텍스트이므로 WCAG 2.1 AA의 4.5:1 기준을 충족하지 않습니다. foreground.inverse는 다크 테마에서 검은색을 선택하고 라이트 테마에서는 흰색을 유지합니다.

수정 제안
            danger: {
                backgroundColor: vars.color.background['danger'],
-                color: vars.color.foreground.staticWhite,
+                color: vars.color.foreground.inverse,
            },
            success: {
                backgroundColor: vars.color.background['success'],
-                color: vars.color.foreground.staticWhite,
+                color: vars.color.foreground.inverse,
            },

다크 테마의 canvas-inverse 매핑을 gray-800으로 수정해야 합니다.

DARK_BASIC_COLORS.gray['800']#dcdcdc이고 gray['900']#fafafa입니다. 현재 Line 194는 #fafafa를 사용하므로 PR에서 정의한 다크 테마 값과 다릅니다. 이 토큰의 소비자는 의도보다 밝은 배경을 렌더링합니다.
