The Game Chat look, 1989
The original 1989 handheld console had a screen that could show exactly four shades of greenish grey. Those four colours became one of the most recognisable palettes in gaming.
Game Chat paints ChatGPT, Claude and Gemini in those four shades with pixel type and frames the app as a handheld. The buttons are decoration; your input works exactly as before.
- Strict four-shade green palette
