Add bgfilter/recolor.py: after despill, propagate clean neighbour chroma into pixels whose colour is still off (residual green, or the magenta a green unmix overshoots into), keeping luminance partway so hair texture survives. It installs a real observed colour rather than subtracting, so it cannot overshoot. Despill already neutralises the matte edge (off ~ 0 there), so recolor only touches the contaminated interior and the wisps the dropout-fill rescued. Runs as a final colour pass on the despilled foreground; pymatting + despill keep their stronger edge handling. On the samples the magenta fringe drops sharply (TestImage vis-magenta 0.065->0.014, TestImage2 0.085->0.031) with edge green unchanged (vis-green ~0.02). Debug output color_mask.png replaces the despill / foreground-background / foreground-correction maps; smoke updated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
