Brahma (/ˈbrɑːmə/; Sanskrit: ब्रह्मा; Tamil: பிரம்மா; IAST: Brahmā) is the Hindu god (deva) of creation and one of the Trimūrti, the others being Vishnu and Shiva. According to the Brahmā Purāṇa, he is the father of Manu, and from Manu all human beings are descended. In the Rāmāyaṇa and the Mahābhārata, he is often referred to as the progenitor or great grandsire of all human beings. He is not to be confused with the Supreme Cosmic Spirit in Hindu Vedānta philosophy known as Brahman, which is genderless. Brahmā's wife is Saraswati. Saraswati is also known by names such as Sāvitri and Gāyatri, and has taken different forms throughout history. Brahmā is often identified with Prajāpati, a Vedic deity. Being the husband of Saraswati or Vaac Devi (the Goddess of Speech), Brahma is also known as "Vaagish," meaning "Lord of Speech and Sound." (Wikipedia)
The complexion of Lord Brahma is red.He is clad in red clothes. Brahma is traditionally depicted with four heads, four faces, and four arms. With each head, He continually recites one of the four Vedas. He is often depicted with a white beard (especially in North India), indicating the nearly eternal nature of his existence. Unlike most other Hindu Gods, Brahma holds no weapons. One of His hands holds a scepter in the form of a spoon, which is associated with the pouring of holy ghee or oil onto a sacrificial pyre, signifying Brahma as the lord of sacrifices. Another of His hands holds a 'kamandalu'- a jar made of metal or even coconut shell, containing water. The water in this jar signifies the initial, all-encompassing ether in which the first element of creation evolved. Brahma also holds a string of prayer beads called the 'akshamala' (literally "garland of eyes"), which He uses to keep track of the Universe's time. He is also shown holding the Vedas and, sometimes, a lotus flower. (Wikipedia)
