Just love eggs---
Not sure if these pictures will help, but I will put some in here...since I have some in my byc picture library..
On the left is my wonderful golden sexlink. Her eggs were the darkest brown, daily and jumbo or extra large. In the middle is one of my BPRs she is pretty consistent and on the right is the other BPR---hers are lighter.
Loads of eggs from my golden sexlink----- IF you want a lot of great eggs, a low cost keeper and friendly bird, you cannot do better than a golden sexlink or golden comet IMO.
Here is a one-time-only one-of-a-kind egg from my BPR that lays the lighter brown. It had brown and blue dots......
All of the above are/were hatchery birds, I believe, I got them from CraigsList.
My colors Left Easter Egger, Top Ideal 236 (Leghorn hybrid) and right and bottom the two BPRs all hatchery birds....... The Easter Egger and the Leghorn Hybrid are good egg layers---- and I got them from Blue Star Ranch....who buys from hatchery and grows them out for folks who either don't want to buy big hatchery orders, are impatient or don't have facilities for chicks.
And my latest one to start laying as of June 15th

First egg from my Cream Legbar........... a bird that I got from HighView Ranch in the Texas Hill country who got it from Greenfire Farms--- rare and unique, this breed will become more readily available in the USA as time goes on.
Hope you get a LOT of egg pictures in response to your question.
