Is black the only color for a funeral?

I am going to a memorial service to honor my mother tomorrow. She passed away in September and has lived a long life. One of the things she enjoyed was for me to help her put together her 'outfits' and to pick out her jewelery to go with the outfits. This process has been going on for a long time.
I do remember once in 1966 helping her get ready for a date with my dad. We spent hours getting the makeup on and the wig combed and teased. I put on those old fake nails that you glued on for her. Her shoes had 3 inch heels and were gold and sparkly. It took me at least 10 minutes to hook up her long line girdle-bra combination because she could not reach them on her side.
Once she was all glammed up and walked down stairs my dad looked at her as she descended and pronounced,"Where is my wife who are you?" . No she didn't kill him but it was not the reaction she was hoping for.
I learned from that event to dress my truth and not to transform myself into something I wasn't.
Tomorrow we are having a service to honor her so I decided to glam up for it just for her. So I bought a new dress with some stones sewn to the neckline. I normally wouldn't go for the sparkly but my mom would have loved it so I 'll wear it in her honor. Normally people would wear all black to a funeral. I gave up wearing black several years ago because I just don't look good in black. It makes me look washed out. So I hope nobody in my family will be offended but I am not going in all black. In fact I will be wearing a blue coat. Is there really a dress code for funerals?
