Not that quick or easy answer.
That brown liquid is supposed to be clear. The blue tube is always the first color that will turn cloudy because the blue wavelength is so intense that it bombards this liquid & eventually destroys it. This is also why you were having color issues (the whites in your picture where probably yellow because of lack of blue making it to the screen)
This liquid is called glycol it's used to keep the tube cool it is conductive & corrosive so if any got on the circuit boards you'll have to clean it all off before ever running the set again.
You'll have to replace the lens & refill that portion with fresh glycol; there is a seal or gasket that goes between that lens & the tube be very careful to not damage it or the new glycol will leak. There is a port on the side of the tube to refill this glycol it looks like a flexible rubber point. It will have to be removed; I think there are 3 screws holding it in place.
They glycol is poisonous (it's like anti-freeze) so wash your hands good after handling it.
It's much easier to refill this with the tube out of the set BUT it's difficult to re-align or converge the 3 colors once the tube has be removed & replaced.
If you decide to remove the tube, Do not remove the high voltage wire from the tube (that leads into the side of the tube) it's the part that looks like a big suction cup, instead remove this wire from the high voltage divider.
If glycol did get on the circuit boards thoroughly wash them with water & dry with rags or sponges then blow dry with hair dryer.
Here is link that describes what glycol is

Hope this helps.
