Does the color of an egg yolk determine the taste?

I was living in Japan for a couple of years and I would often have soft boiled eggs for breakfast. They were always delicious.

When I got back to the states, they didn’t turn out so well. They didn’t taste bad or anything, but they were quite bland.

I noticed one big difference between the eggs. The ones I had in Japan were a much deeper shade of yellow, almost orange.
The ones in the states were a very bright yellow.

Is the difference in the color associated with it’s taste?
How can I determine what eggs will be good?
