¿Por qué no los dos?
Some pictures just work better in black and white, even in India, like the roadside stand in Jaipur on the right. Black and white makes the detail pop in a way it didn't in the color version.
But most of India can only be captured in color, like the picture on the left, which I took from the car on the way back from Keoladeo National Park. I love those lavender and turquoise bricks.
