Light → Dark Mode Converter
Paste your light mode CSS variables. AI generates a perceptually accurate dark mode — not just an inversion.
* Perceptual normalization applied to accessibility standards.
How to convert Light Mode to Dark Mode CSS?
Building a dark mode that looks good and meets accessibility standards is often difficult. Merely inverting colors or picking dark grays doesn't guarantee your text will be readable or your brand colors will be preserved.
Our AI Light Mode to Dark Mode CSS Converter analyzes your light mode CSS variables and uses perceptual normalization to generate a scientifically balanced dark theme. Your accent colors retain their hue, while background and surface colors are accurately skewed for eye-friendly low-light environments.

Frequently Asked Questions
Why not just use invert() or HSL lightness mapping?
Simple math like `%` inversion fails because the human eye perceives colors differently. For example, a pure yellow has very high luminance but poor readability on a white background, whereas the inverted color (dark blue) might look drastically different in context. The AI analyzes color context precisely.
Does this work with standard CSS Variable dark mode?
Absolutely! It takes standard CSS custom properties (`--variable: value;`) and emits the exact same properties, optimized for a dark background. It is framework agnostic.
Is the Dark Theme Generator free?
Yes, using the AI capabilities for generating dark mode tokens is free for all users of TailwindThemeMaker without any sign-ups required.
