Paint-Anything: Unified Any-Color Control for Image Generation and Editing
Summary
Paint-Anything introduces a unified hex‑prompt interface that lets diffusion models generate or edit images with any 24‑bit color per object. Using a mixed supervision pipeline and a new benchmark, it boosts object‑level color fidelity on FLUX.2‑4B by up to 85 % for text‑to‑image and 28 % for editing.
- A data pipeline (Paint‑500K) combines real‑image object grounding, perceptual color labeling, and synthetic edit pairs to train on exact hex colors.
- Pure‑color anchor images are injected only at high‑noise timesteps, preserving natural image learning at low noise.
- The Any Color Benchmark (ACBench) provides object‑level hex fidelity metrics for both generation (T2I) and editing tasks.
- On FLUX.2‑4B, Paint‑Anything raises ACBench‑T2I scores by 85.3 % and ACBench‑Edit by 28.3 % versus the base model.
Engineers building generative image tools need precise, per‑object color control without custom pipelines, and this work shows a practical, benchmarked solution.
