Right component is graphically
色 'color', but here it is the simplified replacement for the original
巴+
刀 (a knife slicing thread). The PRC reform borrowed
色's silhouette as a stylized stand-in; the meaning of 'color' does not enter
绝. Just remember the right side as 'the cutting half', whose original knife and seal-shape collapsed into this 6-stroke unit during simplification.
