Is 6 colors too many?

I wanted to do a pastel pink, blue, orange, green, yellow, and lavender. We have 6 on each side of the wedding party, and I LOVE the idea of each person having their own color. Is 6 too many colors? If so, how do I decrease from there? My fiancée says he’s open to this idea, but he’s not 100%. Any advice? Any worries? Any general opinions!
