Wedding colors

Wedding is next month and bridesmaid dresses are just coming in and I'm not happy with the colors. I was wanting to do blush and dusty purple but the colors are darker than I remember. I obviously have no time to change them but it just sucks its not the vision I had. Am I just over thinking things to much? My florals will be med pinks and purples, even my invitations were blush colored but my bridesmaids and flower girls colors are dark. I'm just worried it won't look cohesive all together.
