Choosing colors for a smaller wardrobe

I am looking for a secondhand jacket to wear through autumn, and narrowing the listings has been harder than expected. Fit seems manageable with careful measurements; color is less clear when every seller photographs the jacket in a different room. Several sellers do not accept returns, so I would rather eliminate doubtful options before arranging a visit or paying postage. The jacket needs to suit both jeans and charcoal trousers, since those are the pieces I actually use each week. I found a page about color analysis and would like to use the idea as a starting point for these comparisons. I am trying to distinguish a versatile shade from one that merely looks appealing in a carefully styled listing photograph. Would asking for a daylight photograph beside a white item meaningfully improve the comparison, or introduce another source of confusion? Seeing the jacket locally would let me compare it with a top I already wear, instead of relying entirely on photographs. I would appreciate a short decision process for comparing jacket colors once condition, measurements, and price have passed the initial checks.
