Pros:

You drip blood when puked on.

Cons:

-Boomer's vomit is still green.
-Hud vomit is still green.
-Does not uninstall by deleting the .vpk. Still have not figured this out.

Conclusion:

This rating would be a 9.5 to 10.0 if everything was done as it should. It seems all you did was change the color of the vomit on the survivors and the color of the vomit-splat on walls. The actual boomer bile vomit is still green, your hud is still green, and this mod .vpk does not uninstall when you delete the file. I cannot get my boomer bile back to vanilla! For now I will have to say this mod is unusable, unless you just don't care about mixed colored puke and never getting it back to normal.
