Paint-Anything: Unified Any-Color Control for Image Generation and Editing
Paint-Anything learns a shared hex-prompt interface for any-color image generation and editing on FLUX.2-4B, improving ACBench scores by 85.3% and 28.3%.
Paint-Anything enables specifying an object's target color as any 24-bit hex value for both image generation and editing through a shared hex-prompt interface trained with object-level color supervision. The authors build the Paint-500K dataset from real images via object grounding, perceptual color labeling, and editing-pair synthesis, supplemented with pure-color anchors used only at high-noise timesteps. They also introduce the Any Color Benchmark (ACBench) with T2I and Edit tracks; on FLUX.2-4B the method improves ACBench-T2I and ACBench-Edit by 85.3% and 28.3% over the base model and achieves the best average CompColor score.
