Black and white definitely dulls the appeal of food. I can't imagine life without color. It's such a big part of enjoying everyday moments. The thought of my kids' artwork appearing in black and white instead of full of vibrant colors is hard to picture. I think that would be the toughest part for me.
I love black and white photography but it doesn't work for everything and this post is a point in case. Also, I agree, I'd not like to see in black and white all the time...it'd be a dull world.
