Light or dark brown particles are varicam glides/pads. They can be replaced by taking off the cam covers. Some have done that with the engine in car but most drop the engine and replace.

Black color particles are the chain tensioner pads. The IMS Shaft to cam tensioner pads on each bank can be replaced (2 on each bank) and the engine will need to be removed. The Ctankshaft to IMS chain tensioner pad cannot be replaced without a total dismantle of the engine.

Check your cam angles and drop your oil pan and take a closer look inside the sump for more debris.
