+## KC-57 — Build error: Color(r:g:b:) used outside its file (coffee brown)
+
+**Status:** Fixed (not build-verified)
+**Reported by:** User (Xcode build errors: "Cannot convert value of type
+'Int' to expected argument type 'Color'", "Extra argument 'b' in call")
+
+### Root cause
+`Color(r:g:b:)` (Double) is declared as `private extension Color` inside
+`DesignTokens.swift` — invisible outside that file by design (only `UIColor`'s
+`init(r:g:b:)` sibling is `private` too, both file-scoped). KC-55/56 used
+`Color(r: 122, g: 84, b: 52)` directly in `SettingsView.swift` and
+`OnboardingView.swift` for the coffee icon's brown background — neither file
+can see the private initializer, so the compiler fell back to unrelated
+overloads and produced the confusing "Cannot convert Int to Color" errors.
+
+### Fix
+Added `AppColors.coffeeBrown` (defined inside `DesignTokens.swift`, where the
+private init IS visible) alongside the other fixed accent colors
+(accent/green/blue/yellow/red). Both call sites now reference
+`AppColors.coffeeBrown` instead of constructing the color inline — matches
+how every other color in the app is centralized, and is accessible from any
+file.
+
+Files: `DesignTokens.swift`, `SettingsView.swift`, `OnboardingView.swift`.
