I know evidence has been posted and I am sure they make some brighter to fool people they are better (people are very visual) but 100% in my experience the more orange the yolk the better it tends to be. I have bought eggs from many european countries and it's always the same. The darker the yolk the harder the shell usually. You can feel the difference when you crack them and they always taste so much better. The worst eggs tend to be an almost grey (with very light yellow) colour. The worst eggs also tend to crack very easily and are very thin. I have also learned you can't always go by packaging as many "free range" are utter crap. Dev in my experience the best supermarket eggs in the UK are happy egg co. or certain supermarket own free range ones.
I hate how some eggs are advertised as coming from chickens eating a vegetarian diet, and people fall for it and pay more. a chicken is not supposed to eat a vegetarian diet, bugs, worms and whatever else lives in the grass is part of their diet.
This is my favorite brand to use but they are pricey, usually $6-$8 per dozen but much better taste than egglands best or other regular brands

These usually have dark yolks but the flavor is much better/stronger than your 79cent per dozen eggs
