Skanda Purana — Prabhasa Khanda, Shloka 31
नीलरक्तेन वस्त्रेण यत्कर्म कुरुते द्विजः । स्नानं दानं जपो होमः स्वाध्यायः पितृतर्पणम् । वृथा तस्य महायज्ञा नीलसूत्रस्य धारणात्
nīlaraktena vastreṇa yatkarma kurute dvijaḥ | snānaṃ dānaṃ japo homaḥ svādhyāyaḥ pitṛtarpaṇam | vṛthā tasya mahāyajñā nīlasūtrasya dhāraṇāt
Quel que soit le rite qu’un dvija accomplit en portant un vêtement bleu ou rouge—bain, aumône, japa, homa, étude védique, libations aux ancêtres—tout devient sans fruit pour lui; même les grands sacrifices sont vains à cause du port du fil bleu (nīla-sūtra).

Type: kshetra
Scene: A brāhmaṇa about to perform homa and pitṛ-tarpaṇa is stopped by a sage who points to blue/red garments and a blue thread; the ritual fire and offerings are shown as ‘ineffective’ until corrected attire is adopted.
FAQs

The teaching is embedded in Prabhāsakṣetra-māhātmya, framing Prabhāsa rites with strict observance norms.
Do not perform religious acts while wearing blue/red garments or the 'nīla-sūtra'; otherwise acts like dāna, japa, homa, and pitṛ-tarpaṇa are declared fruitless.
