I think the OP is just posting examples of color. It appears you like the darker colored goldens. That's what I originally went in search of also, but then I learned that most of the dark goldens are from field lines and do not have the personality that I can handle right now. They are bred to work and hunt and as such have A LOT of energy.
A reputable breeder who I would now call a friend told me that I should really look at many other things before color - primarily temperament, health clearances on the parents, etc.
If you want a dog who will have a job - hunting, field work, etc. - then you might want a field style. But if this is your first golden and you are looking for a good family friend/companion, you might want to look into a dog more from conformation lines.
If color really is important to you, please also consider rescuing. That might be a great opportunity for you to get the color you want and a dog that has a personality that fits with your home and lifestyle.
