Stuck for bridesmaid dress colours

If there ever was a silly sounding problem I feel this might be it. But I am hoping someone has some wisdom or thoughts to help me out.


Before I chose my dress or anything else I knew what flowers I wanted in my bouquet because they will be a replication of the first flowers my H2B ever bought me. Red, ivory and peach/pink roses with sunflowers. I have also added in a bit of lavender to link it to our venue which has lots in the grounds and some baby's breath for tradition!
My dress is champagne and ivory and I am hoping the yellow sunflowers don't clash too much! But now I also have no idea what colour to put my bridesmaids in! It's a summer wedding and pinks feel a bit out of the question as one of my BMs has lovely ginger/red hair and is very pale (I am blonde and very pale too!)
I had found the perfect colour swatch but now the company have stopped stocking that colour! I'm sat surrounded by swatches and no idea what to aim for!
