Changing a planet’s base color is a useful first signal, but it does not make two planets feel like different worlds. For GitHub Planet, we wanted programming languages to be recognizable through surface structure, motion, and silhouette as well as color.
The project turns GitHub profile data into an interactive 3D planet. This article focuses on one design problem: how do you give each language a distinct visual identity without making the planet unreadable?
Make the effect carry meaning
A different color is easy to notice, but it is a weak visual metaphor on its own. We chose a visual idea for each language, then used the shader effect to support that idea:
- TypeScript: a layered, defensive shell around a structured surface.
- Go: flowing atmospheric wind that moves around the planet.
- Kotlin: electric arcs that flicker around the planet’s silhouette.
- Rust: a dry desert surface with drifting dust.
The goal is not to turn every planet into a completely different object. The shared globe keeps the experience coherent; the material and motion make each language feel distinct.
TypeScript: build the identity in layers
The TypeScript planet keeps a textured base surface and adds translucent shell layers. Its shader uses a time uniform to move bands and filaments across those layers. That makes the “typed shell” feel active while the planet underneath remains visible.
Go: make the atmosphere move
For Go, the visual metaphor is wind. A moving atmospheric pattern gives the planet a sense of flow instead of adding another static ring. The direction and timing of that effect are driven by shader uniforms, so the motion is part of the material rather than a separate video.
Keep comparisons fair
A visual comparison is hard to judge if the sample data changes at the same time as the shader. GitHub Planet’s language showcases use fixed sample values, including the same total and weekly commit counts, so you can focus on how the materials differ. They are demo values, not a real user’s GitHub activity.
That small choice makes the showcase useful as a design review tool: change the visual treatment, keep the underlying example steady, and compare again.
Three things we learned
- Start with a metaphor, then choose the shader. “Wind” and “layered shell” lead to clearer effects than “make it glow.”
- Protect the silhouette. Effects should help identify the planet without hiding its surface.
- Keep a stable comparison case. Fixed demo data helps reveal whether a visual change actually improved the language identity.
GitHub Planet is open source, and the language showcases can be explored without signing in.
If you work with Three.js materials or shader-driven interfaces, I’d love to hear how you make visual differences readable without relying on color alone.
