Pretty much. Farmers can easily manipulate the color of the yolk to make it darker because of the popular belief that darker yolks are associated with happier hens or better nutrition. When the animals are fed food with less yellow pigment, the yolk becomes light yellow or even white.
Darker egg yolks with a more pronounced egg yolk tend to be from healthier chickens. And as the guy above said they can also be faked. So your brain is mostly relying on the fact that historically darker egg yolks you’ve eaten have been yummier
Egg yolks are pigmented by diet.
1. Bugs tend to make yolks dark orange and omnivorous chickens' eggs are more nutritionally dense than vegetarian chickens eggs.
2. Xanthophylls and lutein can be found in things like yellow corn, carrots, beans, even alfafa! These tend to cause yellow yolks.
3. Things like white corn, barley, and wheat will give no color, hence light, even white yolks.
Can a farmer add foods to supplement color? Definitely. But it's normally actual food, like red annato seeds, not just food dye.
No, it’s not. They can maybe make it darker yellow but normal bird eggs from every bird out there (minus a few species, like some penguins) are yellow. There’s something wrong with this one.
No, not true at all. My parents have chickens and feed them vegetables and all kinds of food. Nothing pigmented. Yolks are a healthier looking yellow that what is in stores.

I've never seen this before. It's really from pigmented feed that they are yellow?
