Just look at the color of these grapes I got yesterday! I laid them along normal red grapes and some green ones to bring out the deep, rich, almost black color of the plump ones. And these babies are seedless, so off in the blender they go to have a party with some crushed ice!
Random fact-Foods that are deeper in color eg: spinach, tomatoes, pomegranates are higher in anti-oxidant properties. So these things must be loaded, eh?
