Nope, still brown.


Nope, still brown  Less brown, but still brown.

I can see that it's clearly brown, even in the tubing outside of the case where it connects to the radiator.

Those things definitely accentuate the color tint, however.   With more ambient light, a white card behind the tubes, and flash off it looks fairly clear.  It still looks like there's a heavy smoker living in my radiator, and it's still enough to make me want to flush out the system and replacing the tubing.

Prior to this go-round the tubing was a little cloudy/milky white, but it didn't look like literal crap.
