Why do sensuous form, vibrant color, a profusion of ornament, and rich texture dominate indian art?

Because in their culture vibrant colors are very important. Different colors can mean different things. certain textures and colors can mean happiness or other emotions or they can even mean words. It sounds weird but my grandfather's friend Regieve lives in India and he has a lot of cool stories to tell, and he always brings cool trinkets when he comes and visits.
