A Material Dark theme customizer for ChatGPT.

Features
Material Dark, OLED Black, Ocean, Forest, Cursor, Vscode, Matrix, Rose and Nebula Violet and more!
Designed for Daily Use ChatGPT Material Dark lets you customize the parts of the interface you see most: the chat canvas, input area, message bubbles, assistant output, borders, links, headings, and accent colors. Choose OLED Black for a minimal, low glare workspace. Use Deep Ocean, Deep Forest, or Nebula Violet for a softer themed appearance or build and save a theme of your own! Changes appear live, making it easy to experiment with colors and gradients until the interface feels right.
