Color-Code Your AI Agent Terminals Without Leaving Windows Terminal
The hard part of running several AI coding agents is not always orchestration. Sometimes it is simply knowing which terminal is which before you lose your place.
Four terminal workspaces, four visual identities. The work still happens in real terminals.
I keep running into the same problem when I have several coding agents open at once. Claude Code in one window. Codex in another. A local server, logs, tests, and a shell or two beside them. Tab names help a little, but under pressure my eyes still parse the workspace as a pile of similar rectangles.
MatrixShader is the visual layer I built for that problem.
It keeps the work in real terminal windows, but gives each workspace a distinct live Matrix-style shader, color identity, layout, and hotkeys. The point is not to replace the agent, IDE, shell, or multiplexer. The point is orientation.
The Use Case
If you run one terminal, you probably do not need this.
If you run four to eight terminals across agents, projects, logs, and local services, visual identity starts to matter:
- green for the main coding agent
- cyan for frontend work
- red for tests or errors
- gold for database, deploy, or release work
The useful part is that you can recognize the window before reading the tab title.
MatrixShader is not an AI IDE. It does not manage PRs, assign tasks, or orchestrate agents. It sits beside those tools as a visual workspace manager for people who still like running real terminal sessions.
What Ships Now
Windows support is shipped for Windows Terminal with HLSL pixel shaders. Linux support is also shipped through Ghostty with GLSL shaders.
Windows

Linux
curl -sL https://matrixshader.com/linux | bash
The free tier is usable on its own. Red Pill is a paid upgrade for deeper control: live tuning, custom RGB, depth layers, multi-window management, and presets.
Why It Helps
Terminal-heavy work already has enough state: branches, prompts, logs, test runs, task notes, and agent output. A visual cue gives your peripheral vision something to hold onto. You do not have to stop and inspect every pane to remember where you are.
That is the whole bet behind MatrixShader: terminal customization is more useful when it helps you think faster.
