摩訶止觀 9.72

9.72

若內無色相外觀色，若多若少，若好若醜，勝知勝見者：內滅骨人，外有八色；又有依正多少、好醜，如前說（云云）。

Regarding 'having internally no perception of forms while externally contemplating forms, whether many or few, beautiful or ugly, with superior knowledge and superior vision': internally one extinguishes the skeleton, while externally the eight colors remain; and there are also the many or few, beautiful or ugly, of environmental and primary recompense, as described before (and so forth).
