We have Dad's car, a 2000 S430, and the project 2000 S500, both of which have calipers painted black.
Hope this helps for your s280.

2000 S500 (best friend's--now WIFE's--DD: my first W220 project car, once gone to, and now returned from, an excellent home--welcome back home, baby!)
2003 S430 (one of two current DD's--second W220 project car)
2003 S600 (third w220 project car, "sex on wheels")
2005 E320 CDI (the other current DD--first W211 project car)
