I noticed the problem while sorting photos from our last team meeting. Clear navy tops seemed calm, but yellowish neutrals made my complexion look uneven. My hallway mirror showed little change, although window light revealed a clear difference. I have an office presentation coming up and would like to simplify the choice. The plan is one useful addition rather than an expensive wardrobe reset. Instead of ordering samples, I tested six tops beside a simple neutral background. I also removed makeup and kept the camera exposure fixed. The repeated pictures seem to favor cooler colors, and I used this color analysis test page to organize the possibilities. This is only a working theory, and I expect real fabrics to matter more. The practical test will use charcoal, navy, raspberry, and off-white cloth pieces. A useful pair of dependable colors would matter more than the exact palette name. Would you recommend a basic window-light test before I choose the new shirt? I would especially appreciate advice from people who compared results across several days.
