On the example you show above, I think it works against the expanse of gray on the dial. For your Tricolore CS, I'm not as convinced. I think the bright white begs for a more contrasting strap, and the midnight blue will work well in that regard, while also mirroring the blued hands and tying in with the red elements via the stitching.
What do I know?
Follow your joy, my friend. If the tan calls to you, do it! I will enjoy it, as long as you do! 
Be well,
Daos
