It's usual to read that a healthy and balanced diet can be noticed by the colours in a plate. We always try to cook different vegetables here to make our meal full of colours. Try to consume, every day, at least one dish with these different colours: red, yellow and orange, purple and dark blue, green and brown. It's not that easy but you can get better day after day.
Here some example of food by colours:
Red: tomato, red pepper, watermelon, cherry, raspberry, blackberry, papaya, guava.
Yellow and orange: carrot, mango, orange, pumpkin, peach, corn, apricot, banana.
Purple and dark blue: grapes, plum, figs, beets, eggplant, cabbage.
Green: leafy vegetables, broccoli, green pepper, spinach, parsley, herbs, asparagus.
Brown: Nuts, oats, whole grains.
To me the hardest food colours are purple and dark blue because I really don't like some of them. I like grapes, but my husband hates them. The only one I learnt to like in the last years is eggplant. But I can't eat figs or beets. I remember that in Brazil I used to eat beets cooked with beans, but it's not good anyway...
And about you, how many colours has your plate?
