Beautiful blocks!!
I think why everyone likes the darker green is ..(so much from someone who has challenges with color) That color is in the leaves of the floral /the lighter color in the peach one is closer to the pink in the floral. the light green in the green block and the peach colors fight with the floral..the pink and green in the first block look good with the floral and complement it. The white dominates so I would try the dark pink and a light pink (light color in the peach block) and a green with a lighter green in the same color family as the floral has.. I Love your blocks..I would probably end up with 4 quilts
