According to Skanda Purana chapter 9, it was Kalakuta poison which made Lord Vishnu black or dark blue (color of Taamala).

  1. The excellent mountain had adamantine strength. It rolled on the back, neck, thighs and the space between the knees of the noble-souled tortoise. Due to the friction of these two, submarine fire was generated.
  2. The Halähala poison too emerged and it was seen by Närada.

Seeing the deadly poison Kaalkuta, all of them went to Satya Loka as suggested by Bhrigu Maharshi. But even Brahma on seeing the blazing Halalal couldn't help them and they all with Brahma flew to abode of Lord Vishnu.

  1. Then Devas kept Brahmä at their head and hurriedly went to Vaikuntha, because they were afraid of Kälaküta.
  2. Brahmä and others as well as the groups of sages sought refuge in the great lord Vishnu, the primordial Purusha, the mighty lord who had resorted to Vaikunta, Mädhava, Adhoksaja. The groups of Suras and Asuras sought refuge in lord Visou.
  3. By that time, the great poison Kälaküta came there. After burning Brahma's world at the outset, it burned Vaikunta.
  4. Visnu who dwells in the cavity of the heart of everyone, was burned by the fire of Kälaküta also with his attendants. Immediately he acquired the colour of Tamäla.
  5. Vaikuntha also became blue in colour. It was surrounded by all the worlds. Hence, all the worlds became encircled by the poisonous substance from the waters.

Vayu Purana Chapter 54 also describes the same incident.

विषेणोतिष्ठमानेन कालानलसमविषा। निर्दग्धो रक्तगौराङ्गः कृतः कृष्णो जनार्दनः॥ ५९॥

Janardana Visnu who was fair and reddish in complexion has been burnt by the poison that rises with lustre of black fire. He was rendered dark-complexioned.

दृष्ट्रा तं रक्तगौराङ्गं कृतं कृष्णं जनार्दनम्। भीताः सर्वे वयं देवास्त्वामेव शरणं गताः॥ ६० ॥

Having seen that whitish red-hued Janardana, rendered dark-complexioned one, all of us got frightened. We seek refuge under you.

सुराणामसुराणां च श्रुत्वा वाक्यं पितामहः। प्रत्युवाच महातेजा लोकानां हितकाम्यया॥६१॥

Having listened to the Words of the gods and demons, highly radiant Pitamaha Brahma replied, out of desire for the beneficence of the worlds.

शृणुध्वं देवताः सर्वे ऋषयश्च तपोधनाः। तत्तदग्रे समुत्पन्नं मथ्यमाने महोदधौ॥ ६२॥
विर्ष कालानलप्रख्यं कालकूटेति विश्रुतम्। येन प्रोद्भूतमात्रेण कृतः कृष्णो जनार्दनः॥६३॥

"O you Devas, sages and saints, all of you listen. The poison, resembling black fire, that rose up when the great ocean was being churned is known as Kalakuta. Even as it rose up, (Visnu) was rendered black.
