how did local color effect the adventure of tom sawyer's novel??

I'm not totally sure but I'm thinking that you are referring to the setting. Twain put this in the fictional town of St. Petersburg, Missouri; it was supposed to be similar to Twain’s hometown of Hannibal. Local colour is everywhere. The feel of a small town in the Deep South permeates the story. Eccentric towns people like Muff Potter and villains like Injun Jo populate the landscape. There is a sense of laziness, hot summer days and riverside calm. The local language and mannerisms come out as well in the vernacular that the characters use.
