I noticed some blue and lavendar tones in sap oozing from this fir stump, so I took a picture, shifted the result to blue to counterbalance the strong red and orange dominant colors, then increased the saturation to make the present colors more apparent.You may notice in the top left quadrant there is a patch of wood that is dry. It is relatively colorless.

Very interesting.
However, since sap only flows in the Cambium layer of trees, are you sure that the reddish area's colors are from sap -- or maybe a fungus attacking the dead wood (which is what the core of all, or most, trees comprises)?
