Themer
Design a colour theme once and export it for VS Code, Windows Terminal, iTerm2, Alacritty and CSS.
Running here in the page — the same app the desktop opens.

Set a background, a foreground, a cursor and the sixteen ANSI colours, and see them on a live code sample and a fake terminal as you go. The same palette then exports as the real config file each tool wants — a VS Code colour-customisations block, a Windows Terminal scheme, an iTerm2 plist, an Alacritty YAML block, or a set of CSS variables.
It checks contrast as you work and warns when text on the background falls below the WCAG AA threshold, so a theme that looks good does not turn out to be unreadable. Everything is generated in your browser; copy it or download the file.
