fix(mobile): sign-in fields have a visible outline by mapringg · Pull Request #28861 · pingdotgg/t3code

mapringg · 2026-11-01T19:50:21Z

Problem

The native Clerk sign-in input outline is almost invisible. Clerk Android applies 11% alpha to the configured border color, so passing an already subtle near-background color compounds the low contrast.

Change

Use Clerk's default black light-mode and white dark-mode border source colors. Clerk applies its own opacity when deriving input outlines and other borders.

Scope and approval

Submitted as a small, focused fix of an obvious native input-visibility defect, with no prior issue. Only the two existing theme border values change; no authentication flow changes. The iOS Clerk mapping is unverified.

Verification

Android API 36 emulator in dark mode, using public Clerk configuration and no signed-in account. The baseline is the previously installed upstream native client; the after image uses a dev client rebuilt from this branch. The served Metro bundle was refreshed and native generated resources checked. Clerk Android source confirms INPUT_BORDER_ALPHA = 0.11F in ClerkComposeTheme.kt and black/white default border colors in ClerkThemeProvider.kt. Native build: T3_NATIVE_CLIENT_CACHE=off node_modules/.bin/vp run mobile:install android --prepare succeeded (3m 26s), followed by node_modules/.bin/vp run mobile:install android emulator-5554. The APK's assets/clerk_theme.json exactly matches this branch. Light mode and the iOS mapping remain unverified.

node_modules/.bin/vp run check:changed passed at this branch head in the previous session; Sol review approved the diff. No fix code changed during evidence collection.

Before — sign in	After

Clerk source: input border alpha, derived input border, default border colors.

Code written by Claude Opus 5.5; evidence and PR filing by GPT-6.1 Sol, both in T3 Code.

Layer / File(s)	Summary
Update theme border colors `apps/mobile/clerk-theme.json`	The light theme border changes from `#e4e4e7` to `#000000`. The dark theme border changes from `#191919` to `#ffffff`.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Bug fix

Merge Risk: Low · up to 89234

Normal builds retain the improved outlines, but regenerating themes will restore the old colors. Align the generator to prevent losing the fix.

Full details: Title check

Explanation

The title "fix(mobile): sign-in fields have a visible outline" matches the changeset. The raw summary shows the light and dark theme border colors in apps/mobile/clerk-theme.json change from #e4e4e7 and #191919 to #000000 and #ffffff. The PR objectives say this change targets the nearly invisible native sign-in input outline. The title is concise, follows conventional commit form, and names the primary change from the user's perspective.

Full details: Description check

Explanation

The description follows the template structure. It has Problem, Change, Scope and approval, and Verification sections, plus the before/after screenshot table. The Problem section states the defect and cause. The Change section states the fix. The Scope section explains why no prior issue exists, which the template allows for a very small, focused fix of an obvious bug. The Verification section lists the emulator checks, build command and result, and the APK asset comparison. It also states what remains unverified, namely light mode and iOS. The template's linked-issue or maintainer-approval requirement is addressed by the small-fix exemption, though a reviewer may question whether an obvious-bug exemption applies to a color change with an unverified iOS mapping. Minor gap: the Problem section does not give explicit reproduction steps beyond the environment, and the description does not include the template's preamble checklist item about CONTRIBUTING.md.

Update the generator source, then regenerate clerk-theme.json.

apps/mobile/clerk-theme.json is generated from the default theme border values. Those values are still #e4e4e7 and #191919, so regeneration overwrites the changed Clerk borders. Make the Clerk-specific generator output #000000 and #ffffff, then regenerate the file.

Suggested fix

- border: variables["--color-border"], + border: appearance === "dark" ? "#ffffff" : "#000000",
