SUMIRO

One extension. Multiple editor aesthetics.
A curated collection of OLED-black, dark, and light color themes for Visual Studio Code and compatible editors.

Independent theme collection by Yuvraj Rastogi

SUMIRO brings several visual styles together in one extension, so you can switch between them without installing a separate theme extension for every look. Choose a deep dark workspace, a true-black OLED variant, or a clean light palette from the same theme picker.

Independent project: SUMIRO is not affiliated with, sponsored by, or endorsed by Cursor, Vercel, Microsoft, Apple, or their respective products. Their names are used only to identify the design inspirations or theme variants. See Third-party notices.

Why SUMIRO?

• One install, many styles. Keep the theme families you like in one extension.
• OLED-focused options. Selected variants use a pitch-black #000000 workspace background, with complementary UI colors chosen for separation and readability.
• Dark and light choices. Switch visual styles without managing several separate theme extensions.
• A consistent theme picker. Find variants by searching for terms such as OLED, Cursor, Vercel, VS Code, or Xcode.
• Theme-only. SUMIRO provides color themes; it does not need to run a background service or collect your project data.

Color appearance and contrast depend on the selected theme, editor, display, and user settings. OLED-black backgrounds do not guarantee lower eye strain or accessibility for every user.

Theme collection

SUMIRO currently defines 20 themes across four visual families. Names below describe the collection; the exact visible labels are defined in package.json.

Cursor-inspired themes

Vercel-inspired themes

VS Code-inspired themes

Xcode-inspired themes

Names that refer to other products describe visual inspiration or a palette family, not official endorsement. Availability and rendering can vary across compatible editors.

Installation

Visual Studio Code

After SUMIRO is published to the Visual Studio Marketplace, install it from the Extensions view:

1. Open the Extensions view with Ctrl+Shift+X on Windows/Linux or Cmd+Shift+X on macOS.
2. Search for SUMIRO.
3. Select the extension published by yuvraj-rastogi, then choose Install.

You can also install it from a terminal after publication:

code --install-extension yuvraj-rastogi.sumiro

Cursor and other VS Code-compatible editors

Extension-registry support differs by editor. Search for SUMIRO in the editor's configured registry. If it is not listed, check whether that editor supports Open VSX or installing a .vsix file manually. Compatibility is not guaranteed merely because an editor is based on VS Code.

Apply a theme

1. Open the theme picker with Ctrl+K Ctrl+T on Windows/Linux or Cmd+K Cmd+T on macOS.
2. Search for OLED, Cursor, Vercel, VS Code, or Xcode.
3. Preview a theme, then press Enter to apply it.

You can return to the same picker at any time to switch themes. Theme labels may be updated between releases; use the names displayed by your installed version.

Compatibility

SUMIRO uses the standard VS Code color-theme contribution format. It is intended for Visual Studio Code and compatible editors that support these theme contributions. Individual editors may render UI colors differently or omit some theme color keys. Test your preferred theme in your own editor and version.

This project does not claim compatibility with every VS Code-derived editor or every web/remote environment.

Feedback and contributions

Found a missing color, unreadable token, or editor-specific rendering issue? Use the repository’s Issues link in the extension’s Resources panel and include:

• The exact SUMIRO theme name.
• The editor and version you use.
• The language or UI area affected.
• A screenshot, if it helps explain the issue.

Please do not include passwords, tokens, private source code, or other sensitive information in screenshots or issue reports.

Contribution proposals are welcome, but please open an issue first for substantial palette changes. Do not submit theme files or assets copied from another project unless their license permits the proposed use and the source is documented.
