Bride Emails Ginger Bridesmaid Demanding She Dye Hair

(Dailymail)
Ever since this story was posted on Reddit, it has been causing a lot of controversy. The post has since been deleted, but the bridesmaid who shared the post explains how her friend (the bride) emailed her requesting she dye her (naturally) red hair brown for the wedding:

“You’ll need to dye your hair for the day, I’ll take you to my hairdresser and cover the cost.”

Bridesmaid says:
“This had never been mentioned to me. I’m a natural ginger, so it’s not like I have an outrageous hair colour, although Ella and her other bridesmaids are all brunettes. I texted Ella about it, she told me my hair would clash with the wedding colours and that brides get a veto over pretty much every aspect of her bridesmaids’ appearances. She also mentioned my hair is quite “attention-grabbing” and I’d take away from the cohesiveness of the group. I told her I wasn’t comfortable dying my hair. She said she’d get back to me but hoped I’d reconsider. Am I being reasonable here? I’ve never been involved in a wedding before so I’m not quite sure what’s expected of me. I’ve gotten some messages from the other bridesmaids who are telling me I should just do it.”
