So, if you want a for sure colorful egg basket, here's some options to consider:
From Hoovers Hatchery (I have some of these):
Prairie Bluebell Egger (lays light blue eggs most of the time, 15% chance of a tan egg. I have one of 6 that has a greenish tint and 1/6 that is so light it's nearly white. The rest are a light powder blue, not vivid, but blue if you put them in a white egg carton). Eggs are medium to large, I have some that lay almost extra large but not quite, and one that persists in laying medium. Lays about 5 days per week. These chickens are active, flighty, curious, and intelligent, would be great foragers, but you can confine them too. ~4 lb hens. They are a hybrid, so don't breed true, but I liked knowing what color their eggs would be when I bought them. Basically a fancy, hatchery created version of an easter egger.
Starlight Green Egger (lays green eggs, I think 15% chance of a tan egger?) Eggs are medium, lays 6-7 days a week. Mine lay 7 days a week, but miss a day about every week or two. Beautiful regular kind of pea soup green color that's almost olive. Definitely different than the sage green ones you have. One of my SGEs ended up laying tan, but it's a pretty light tan, and I'm keeping her because she lays every single day, one large egg. Can't argue with that. Another fancy hatchery easter egger.
Some I don't have but plan to get:
Green Queen (hatchery mix green egger). I've heard it's a Faverolle mix, very pretty. Another fancy hatchery easter egger.
Whiting True Blue (an actual breed, sold by murray mcmurray, developed by Tom(?) Whiting to lay many large to extra large brighter blue eggs). They breed true for blue eggs. I think they don't have, or only have the occasional green tint to their eggs.
Whiting True Green (another breed created by Tom Whiting) lays many large to extra large sage green eggs. They breed true as well.
Chicken math is fun to practice.
