Not yellowish, I think.

This is growing on a very iconic Noble fir stump/burl, without bark, growing immediately adjacent to the trail to Sheppard’s Point. It is about 40 feet below the viewpoint. The fact that I could photograph it means it is on the eastern side of the burl. The southern side is very steep and unsafe. The viewpoint at Sheppard’s Point is on a cliff-face, about 300 feet high. The sides of the point are only slightly less steep.

I was trying to get the contrast between the exposed pinkish Noble fir burl wood, and the lichen.
