Serious Eats did a taste test between home grown and store bought eggs. They found that if they added food coloring to the store bought eggs to make the color more orange like the home grown eggs, that taste testers were just as likely to prefer the store bought.
It's not just about the taste is it? I'd eat junk all day, if I only cared for the taste. Different color (without food coloring) signals different nutrients: https://www.justchartit.com/egg-yolk-color-chart/
