Remove Warm Cast from Google Nano Banana Outputs
Google Nano Banana excels at generating character art and scenes with consistent styles, but an inconsistent yellow tint can break that promise. You might generate a sprite sheet or series of images, only to find each one with a slightly different warm hue. This destroys visual continuity and makes your final project look unpolished. UnYellowGPT solves this by neutralizing the color cast across all images, so every piece in your series shares the same true colors.

UnYellowGPT is purpose-built to solve the exact color challenges posed by Google Nano Banana.
Inconsistent Color Across Assets
Variable warm tints mean each image feels like a different time of day. Characters or scenes drift in color temperature, breaking the cohesive look. This undermines the consistency Nano Banana is known for and forces extra work to manually match colors.
Batch Color Harmonization
Run your entire Nano Banana image set through UnYellowGPT at once. It automatically standardizes the white balance for every image, aligning their colors to a neutral baseline. The result is a uniform palette and seamless integration across the entire series. No manual tweaking needed.
