The "Color Anchor Node Flux2Klein" is a custom ComfyUI node designed to address color drift issues that occur when using FLUX.2 Klein for image editing. When using a reference latent, the model gradually overrides its color statistics as sampling progresses, causing drift away from the reference — especially noticeable in short 4–8 step schedules. The node hooks into the sampler's post-CFG callback and after every denoising step measures the difference between the model's predicted color and the reference latent's color, nudging it back — while only correcting the color (DC offset), leaving structure, edges, and textures completely untouched.
