Galet is a beautiful neutral and it would look very elegant with the colors you wear. I nearly purchased it in September, but I prefer gold hardware to silver. I purchased the SC PM in Galet with gold hardware instead and love it. Both bags are timeless beauties! I do think the difference in hardware very slightly affects the overall appearance. With silver, Galet reads a little more cool- toned. The gold hardware on the SC slightly " warms up" the color of the leather.
To answers your original question, choose Galet! You'll always be able to find a lovely black bag, but this gorgeous, light neutral works with everything and is classy and different. I wore mine with dark denim and dark colors all winter and it looked beautiful. Also, no color transfer at all, and that was a concern of mine.
