Themery

Themery is an experimental tool that lets users create custom color themes for integrated development environments using AI assistance. It provides controls for adjusting colors, syntax highlighting, and typography, and it relies on perceptually uniform OKLCH color space and APCA contrast scoring to ensure visual consistency and accessibility.

The interface allows fine‑tuning of theme elements and supports exporting the finished theme to a range of editors, including Visual Studio Code, JetBrains IDEs, Neovim, Helix, Zed, and others. Users can generate a theme once and apply it across multiple environments with a single click.

Designed for developers who want to personalize the look of their coding environment, Themery focuses on the technical aspects of color engineering rather than marketing claims, offering a straightforward workflow for building and publishing IDE themes.
