"The colours used by the Indian craftsmen for their textiles, writes Robinson, were not only brilliant and of great variety, they were also often exceedingly subtle and particularly so in their tonal qualities: Their colours seem to contain hidden qualities and effects that only appear in differing lights. The pagris or headwear produces in Rajasthan (originally Rajputana), Kotah and Alwar contained two slightly differing shades which produced a constantly changing colour pattern as the fabric rippled."
