Danny White d067e81a69 fix(ui): align primary colours across text, buttons, and controls (#50697)
## Problem

Primary colour serves readable text and selected controls, but those
uses need different shades. Light mode needs darker text, while dark
mode needs a deeper button fill. Fixed brand green on interactive chrome
also prevents a custom primary hue from carrying through the interface.
Some slider tracks and selected text are hard to read.

## Solution

- Keep `--primary` for accessible text and small selected indicators.
Use `--primary-solid` for button fills, which need a deeper shade in
dark mode.
- Add `--primary-bright` for focus rings, selected control chrome, chart
accents, and other interactive highlights. It follows `--primary-hue`;
`brand-*` stays fixed for Supabase identity.
- Make slider troughs clearer and text selection translucent with theme
foreground text.
- Document the split in the design-system colour guide.

## Review instructions

1. Compare light and dark mode in the [colour usage
guide](https://design-system-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/design-system/docs/color-usage#primary-and-brand-colors).
Check primary ink, primary-solid, primary-bright, and fixed brand
swatches.
2. In Studio, open the ‘new table’ sheet in [Table
Editor](https://studio-staging-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/dashboard/project/_/editor).
Tab through the new table sheet's fields and toggles. Check the focus
rings, selected controls, and the sheet's edges in both themes. You do
not need to save a table.
3. Select text in Studio in both themes, including a link or
primary-coloured label. The selection and text should remain legible.
4. Check the
[Field](https://design-system-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/design-system/docs/components/field)
Price Range slider: the unused track should remain visible in both
themes. The selected field card border should follow primary-bright.
5. Check the
[Button](https://design-system-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/design-system/docs/components/button)
and [Radio
Group](https://design-system-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/design-system/docs/components/radio-group)
previews. In dark mode, `primary` button fill should be deeper than
primary
[text](https://design-system-git-dnywh-fix-bright-brand-chrome-supabase.vercel.app/design-system/docs/color-usage#text);
selected radios should remain readable.

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
