Color memory in generative models
Why models drift away from a specified palette, and how to make colour stick.
Noetic Lab

The palette won't hold still
Ask for a precise brand colour and models tend to drift toward their training average. Colour memory is the problem of making a specified palette persist through generation.
We condition on palette anchors and penalize drift directly, so a brand red stays the brand red instead of sliding toward whatever the model saw most often.
