The Complexion of Kulasundaree Nitya is said as Lohitaangee. Lohita is red as well the colour of the Copper. Normally for red Raktavarnaam is used and hence it is correct to consider as the complexion is of Copper. Lohitaakaara is used. Aakaara is the shape, form and hence it cannot mean the colour. Lohita also gives the meaning as Snake, serpent and hence the Devi is served by the Shaktis in the shape of Serpents. Her garments, ornaments are red in colour. Her six faces resemble the Lotus flower. She shines resplendently in her Ruby set crown studded with rare jewels and gems. She is very auspicious. Seated on red Lotus she is highly blissful and showing her grace on her devotees. She holds coral rosary garland, lotus, jewel studded bowl, jewel filled bowl. Citrus fruit, book, red lotus, gold stylus, jewel garland, conch in her 1o hands, the other two hands are showing Vyakhyana Mudra that is gesture of explanation and the varada Mudre, that is boon granting gesture. She is eulogized by the Gods, Gandgarvas, Yakshas, Rakshasas, Daityas, Sages, Siddhas and Vidyadharas.
Kulasunadaree Nitya graces her devotees with the wealth of speech and radiance.

Rakshasas and daityas are separately mentioned because daityas are those who have a immeasurable body. Vidyadahras are referred to great Scholars.
