Choosing colors for a community clothes swap

[Noahramb]

My next sewing project is a simple blouse, and I am trying to choose the fabric more carefully this time. Construction is not the problem at this stage; comparing shades from photographs is the part that keeps delaying me. There is enough time to order swatches, and I would rather compare a few properly than buy several unnecessary lengths. One idea I am exploring before ordering the samples is personal color analysis though I still want the final choice to work with the clothes I already enjoy wearing. Would you start with three related shades, or include a deliberately different option to make the comparison clearer? The samples will only be small squares, so I need to account for the larger area of the finished garment. I would appreciate a practical method from anyone who chooses fabric with both personal coloring and an existing wardrobe in mind.
