# Editing - Color, Structure, Sync

Color bar operations (WarpColor/WeftColor): Always color-only. Never touch structure or thickness. Sync \
  checkboxes are completely ignored.\
\
  Structure operations (Warp/Weft): This is where Sync matters:                                         \
  \- Sync Color ON → operation also affects colors alongside structure\
  \- Sync Color OFF → operation only affects structure, colors untouched\
  \- Sync Thickness ON → operation also affects thickness alongside structure\
  \- Sync Thickness OFF → thickness untouched

 

  This is one-directional — sync only flows FROM structure TO color/thickness, never the reverse.
