That's a good point. I was thinking about similarity between tomatoes and eggs, where a free range egg, especially where the farmer let's the chickens have the run of the farm, have much brighter and deeper colored yolks. I had understood this to relate to the chickens diet and the nutrition of the egg. So I imagined deeper brighter red tomatoes to be similarly more nutritious. It could be different mechanisms though, or maybe neither is more nutritious, they just look nicer.

It is common to add sources of yellow and orange to chicken feed, for both free range and caged chickens. Two quotes from an internet page: "The yolks in my certified organic birds vary in colour. Because the public expect deep yellow/orange yolks in free range eggs I supplement mine with organic vege scraps. You don't need very much to make a difference. Just toss them the odd pumpkin." "The intensity of yolk colour may be measured against standards such as the DSM Yolk Colour Fan. Most egg marketing authorities require deep-yellow to orange-yellow yolk colours in the range 9 to 12 on the DSM Yolk Colour Fan. Yolks of more intense colour may be required for specific markets. The most important sources of carotenoids in poultry feed are maize (corn), maize gluten, alfalfa (lucerne) and grass meals; these sources contain the pigmenting carotenoids lutein and zeaxanthin, which, together with other oxygen-containing carotenoids, are known by the collective name of xanthophylls."

I actually don't make that much difference in taste between free range eggs, even home grown, and the industrial kind. The yolk is usually brighter, but not always. The real difference is usually the shell, which is much thicker and harder for free range eggs. Home grown tomatoes on the other hand are way better tasting. I don't know about nutrition value.
