Useful questions for a first personal color analysis

My sister is planning an intimate autumn ceremony with softly cool colors. There will be people with very different coloring and style preferences. Nobody wants to choose a color just because it photographs as a trend. We may use a family of smoky blue, muted berry, soft charcoal, and silver accents. To give the discussion some structure, I looked at soft winter color palette while keeping in mind that personal preference still matters. That might let us choose related fabrics that still give each person some choice. I want to see the proposed colors near each other in natural afternoon light. Did anyone here manage different personal palettes around one event color family? We are also keeping the venue and season in view, because a color that looks elegant on a digital board can change once it meets warm wood, candlelight, and autumn flowers. The aim is a relaxed group photograph, not a technical demonstration of a palette. Comfort matters too, since everyone will be wearing these choices for a long day.
