Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
नानावर्णः स पार्श्वेषु पूर्वान्ते श्वेत उच्यते पीतं तु दक्षिणं तस्य भृङ्गिपत्त्रनिभं परम् उत्तरं तस्य रक्तं वै इति वर्णसमन्वितः //
nānāvarṇaḥ sa pārśveṣu pūrvānte śveta ucyate pītaṃ tu dakṣiṇaṃ tasya bhṛṅgipattranibhaṃ param uttaraṃ tasya raktaṃ vai iti varṇasamanvitaḥ //
He is described as multicolored on the sides: at the eastern end he is said to be white; on his southern side he is yellow, like the wing of the bhṛṅgi bee; and on his northern side he is indeed red—thus endowed with the prescribed colors.
This verse is not about Pralaya; it belongs to iconographic instruction, prescribing how sacred forms are colored according to direction (east/south/north).
It supports dharmic duty indirectly: kings and householders who sponsor temples and rituals are instructed to follow correct iconographic standards (directional colors) to ensure rites are performed in accordance with śāstra.
It encodes directional symbolism used in temple painting and image-making: the icon’s eastern aspect is white, southern is yellow, and northern is red—guidance relevant to vastu-aligned placement and ritual correctness.
