## Summary
|
|
|
|
The authoritative built-in light theme for Telegram Desktop: white incoming bubbles against pale-blue outgoing bubbles, grey/blue in-bubble timestamps, translucent service pills, and a fixed 8-hue peer palette for sender names and avatars. Every value below is an exact hex from the file.
|
|
|
|
## Key findings
|
|
|
|
- Message bubbles: incoming `msgInBg #ffffff`, outgoing `msgOutBg #def1fd`; selected-bubble overlay `#bbe1fc`; bubble shadows `#748ea229` / `#0d5a911a`.
|
|
- Message text is near-black (`windowFg`) on both bubble sides.
|
|
- In-bubble time color: incoming `#a0acb6`, outgoing `#86a8c2`.
|
|
- Service pills (date dividers, service messages): `msgServiceBg #00518059`; date pills render `{month} {day}` or `{month} {day}, {year}`.
|
|
- Unread bar: background `#fcfbfa`, foreground `#538bb4`.
|
|
- Chat-list unread pill: `#40a7e3`, muted `#bbbbbb`, white text; name `#222`, snippet `#999`.
|
|
- Group sender-name peer palette (8 hues): red `#c03d33`, green `#4fad2d`, yellow `#d09306`, blue `#168acd`, purple `#8544d6`, pink `#cd4073`, sea `#2996ad`, orange `#ce671b`; the same hues in different tones drive avatar gradients.
|
|
- Top bar background and compose background are white.
|
|
|
|
## Pros / strengths
|
|
|
|
- Authoritative source: the actual shipped built-in theme, not a teardown or guess.
|
|
- Exact hexes for every role, with a matching night file so day/night pairs can be compared key by key.
|
|
- The 8-hue peer palette is the canonical answer for sender-name coloring.
|
|
|
|
## Cons / limitations / caveats
|
|
|
|
- Desktop only: iOS, Android, and Web default hexes were not verified against this file and may differ.
|
|
- A key/value theme file carries no geometry: bubble corner radii, paddings, inter-message spacing, and tail shape are not in evidence from this source.
|
|
- Key semantics have to be inferred from names; the file alone does not say how each key is rendered.
|
|
|
|
## Relevance to tai
|
|
|
|
Canonical light-theme defaults for the Telegram look-and-feel decisions: bubble/ink/time hexes, service-pill treatment, unread-pill colors, and the peer-name palette tai's chat scene should mirror (as rows, per the rows-not-bubbles decision).
