wedding COLORSS

Planning my own wedding so far has been going great we have a year to go reserved a hall and looking for a place to have the ceremony, but, now ive run across the bridal party dresses. I think they have decided on a dress however its suppper hard to find the color. so I need help!! is there another name for blueberry because i cant seem to find a lot of bridesmaid dresses in 'blueberry' they have dark blue indigo and all that otehr stuff but not BLUEBERRY ugh! my fiance isnt letting the girls pick any other dress unless the color says blueberry on the tag lol ((kinda a groo-zilla)lol) but im not sure what to do..
