About CoolClaude
Bot Upgrade Module: Customize the background color of Claude.ai.
Humans love Claude, but they also like their bots with drip. Since the definition of "drip" varies by individual, this extension lets you choose. It doesn't affect the colors of text, Claude's persona, or code. It only affects the background. It doesn't collect data and it doesn't care about your interactions with Claude. It stores colors you set in presets. It only works on Claude.ai.
It's a light-touch way of making your many hours spent on Claude more enjoyable.
