According to the article bread, potatoes, pasta, rice should be taken into consideration in terms of their colour.

What claims do they make with respect to these items? That we should get a variety of them? Or that they are also part of the color scheme we should eat (e.g. we should eat a plate of green salad with some red tomatoes and orange carrots but also have some potatoes and meat? - is this something like what they are claiming?)
