Explanation:

In this art, the representation of deities like Kali and Lord Ayyappa, are made on the floor. Various factors need to be considered when deciding the nature or figure on the 'Kalam',which include the presiding deity of the temple or sacred grove, the religious purpose that calls for the ritual of Kalamezhuthu and the particular caste that does it.In each case the patterns, minute details, dimensions and colour choice are decided in observance with strict rules. The patterns vary considerably depending on the occasion, but rarely by the choice of the artist.
Kalamezhuthu is practiced using natural pigments and powders, usually in five colours.The drawing is done with bare hands without the use of tools. The pictures are developed from the centre, growing outwards, patch by patch. The powder is spread in the floor, letting it in a thin stream between the thumb and the index finger.The figures drawn usually have an expression of anger or other emotions. The powders and pigments are all extracted from plants .
