Origin
This phrase originated with the Roman Empire. Roman soldiers used to wash the walls of a newly- conquered town or city with the blood of the vanquished. This was usually accomplished with a great degree of gusto, hence the term being applied to a great night on the town.
In the 19th century, the section of town where brothels and saloons were located was known as the red light district. So a group of lusty cowhands out for a night on the town might well take it into their heads to make the whole town red.
Paint the town red is a reference to the money spent in the process. The party goer ends up in the red paying for the celebration. Related phrase: In the red.
A joke that the resulting blood-shot eyes resulting from partying and drinking might actually color one’s field of vision red.
