+# SAP Quartz Theme for VS Code
+
+Color themes that bring the SAP GUI Quartz look & feel into Visual Studio Code — including full ABAP and CDS syntax highlighting.
+
+Both themes are derived from SAP's official [`@sap-theming/theming-base-content`](https://github.com/SAP/theming-base-content) package, using the exact color values from `sap_fiori_3` (Quartz Light) and `sap_fiori_3_dark` (Quartz Dark).
+
+## Themes
+
+| | SAP Quartz Light | SAP Quartz Dark |
+|---|---|---|
+| Source | `sap_fiori_3` | `sap_fiori_3_dark` |
+| Shell | `#354a5f` | `#354a5f` |
+| Editor background | `#ffffff` | `#29313a` |
+| Text | `#232629` | `#fafafa` |
+| Keywords | `#0a6ed1` | `#91c8f6` |
+| Strings | `#107e3e` | `#abe2ab` |
+| Types / Classes | `#c0399f` | `#e269c9` |
+| Methods | `#286eb4` | `#6bd3ff` |
+| Constants | `#d08014` | `#ffc847` |
+| Comments | `#6a6d70` | `#d3d7d9` |
+
+## Installation
+
+Download the latest `.vsix` from [Releases](../../releases), then:
+
+```bash
+code --install-extension sap-quartz-theme-1.0.0.vsix
+```
+
+Or inside VS Code: **Extensions** (Ctrl+Shift+X) → `⋯` menu → **Install from VSIX…** → select the file.
+
+Activate with **Ctrl+K Ctrl+T** and pick **SAP Quartz Light** or **SAP Quartz Dark**.
+
+## Color Mapping
+
+Every UI color maps to an official SAP theming parameter:
+
+| VS Code element | SAP parameter |
+|---|---|
+| Title bar / Activity bar | `sapShellColor` |
+| Side bar | `sapShell_Background` |
+| Editor background | `sapBaseColor` |
+| Tab accent | `sapBrandColor` |
+| Status bar | `sapPageFooter_Background` |
+| Input fields | `sapField_Background` / `sapField_BorderColor` |
+| Lists & selections | `sapList_*` |
+| Errors | `sapNegativeColor` |
+| Warnings | `sapCriticalColor` |
+| Success / strings | `sapPositiveColor` |
+| Info / links | `sapInformativeColor` |
+
+Syntax token colors use the `sapAccentColor1`–`sapAccentColor10` palette from the same theme, mapped as follows:
+
+| Token | Light | Dark | SAP parameter |
+|---|---|---|---|
+| Keywords (DATA, SELECT, IF…) | `#0a6ed1` bold | `#91c8f6` bold | `sapBrandColor` |
+| Types (zcl_*, dfkkop, abap_bool) | `#c0399f` | `#e269c9` | `sapAccentColor4` |
+| Methods / functions | `#286eb4` | `#6bd3ff` | `sapAccentColor6` |
+| Strings | `#107e3e` | `#abe2ab` | `sapPositiveColor` |
+| Constants / numbers | `#d08014` | `#ffc847` | `sapAccentColor1` |
+| Storage (DATA, TYPES, CLASS) | `#925ace` | `#b995e0` | `sapAccentColor9` |
+| Annotations (@, decorators) | `#925ace` | `#b995e0` | `sapAccentColor9` |
+| HTML/XML tags | `#d04343` | `#e7a1a1` | `sapAccentColor2` |
+| Regex | `#0f828f` | `#7fc6c6` | `sapAccentColor7` |
+| Namespaces | `#6367de` | `#8ca7d5` | `sapAccentColor5` |
+| Comments | `#6a6d70` italic | `#d3d7d9` italic | `sapContent_LabelColor` |
+
+## How It Was Built
+
+1. Installed `@sap-theming/theming-base-content` from npm
+2. Parsed `variables.json` from `content/Base/baseLib/sap_fiori_3/` and `sap_fiori_3_dark/`
+3. Mapped SAP design tokens (`sapBrandColor`, `sapShellColor`, `sapAccentColor*`, etc.) to VS Code's `workbench.colorCustomizations` and `tokenColors`
+4. Packaged as a standard VS Code color theme extension
