With my cheapo 30 scope if I do not zoom perfectly the trichs do not appear the correct color.
I think they take on the surrounding colors. My guess is that you can see more clearly in person than we are seeing in those pics.
It sounds weird but when I have focus on a small group of trichs the ones near that area look amber until i zoom on them correctly and they then appear as they actually are. All I`m saying is based on the pics you posted I would be hard pressed to give an honest answer.
