Symbolism in Camus novels play an important role, he uses different symbols to highlight different realities and uncovered different truths, he was a naturalist as well because of his love for nature, he added them as a result in his writings.
 There have been used various symbols including Sun the first and foremost major and quintessential symbol, at the same time different colors have used including red, green and white, the courtroom. Sunday, Arabs and Crucifix.
While discussing the symbol of the sun, it shows Meursault's discomfort towards reality and his absurd feeling towards it, because whenever something happens to him Sun shines, sometimes he basks in it and another time he rebels it. It depicts the reality of the universe that man negates, and when it collides with man it creates absurdity. The bright light of sun shows indifferent behavior of Meursault towards nature, as when the flashing light of sun glared on his face he tries to hide his face, but when he finds out and confronts the absurdity of life he accepts it, although in various occasions in the novel he says to his coworker to turn off the light, he is more insensitive towards light than his mother’s funeral. That same light at the end of the novel become his friend because he accepts everything. The murder of Arab happens also in the sunlight, and the reason why he kills is because of sun, Arab also depicts his Sun-father. when he wishes it he wills Homoerotic relation with him and in final chapters, he attains comfort in nature by calling nature his 'brother’, so he befriends and becomes comfortable with its scheme. Nature appoints Meursault as an agent to destroy other beings as Sade remarks, according to him the reason behind his murder was nature destructive force, that is why when the court asks for the reason he is unable to defend himself and says 'It just happened that way''. Because nature was the driving force behind him.
 At the same time, sunlight on the sands and rivers made it more difficult for him to swim, see, walk and enjoy moments
Another symbol that has been used is of Sunday, it signifies various things, as it is the symbol of Christ death, her mother’s funeral, killing of Arab, all the major incidents happened on this particular day, at the same time he is put to death on the same day, Christ and Meursault are similar in front of some scholars as some calls him as ''Christ as a human version of being, he shows the new testament of Christs in which he drinks alcohol and commits murder as human beings do frailty.
While discussing the courtroom, it symbolized the society that contains order and rationality, but within a courtroom, he felt indifferent because they always inquire and investigate rational questions and are limited in their psyche.

Different colors have been used in the novel, like red, green, white, that shows different aspects of Meursault and the universe and the connection of them with him, when he is angry, he becomes red and when in a calm mood the sky is shown as green because it symbolizes calmness, peace, and tranquility. the white color shows light of a sun that is unbearable, so the different colors of nature are variables that show certain human versus weather conditions.

The sign of Crucifix is used as a sign of Christianity, as some of the scholars agrees upon the fact that he was more agnostic than Atheist and more non-Christian than Anti-Christ, as we can see in the novel he was called as ''Monsieur Antichrist'' because of his refusal to the existence and believing in God. by refusing him, people have refused to message of god because he was the Christ human version. In front of him, religion is a limitation a restriction that made people think in a certain way that is the case with Chaplain, in front of him he lacks his ability. Therefore, he is the depiction of Christ. and the dinner with Raymond is also symbolical in a way all the tragedy and destruction starts from that point. The bread and wine hosted by Raymond symbolized as Christ's blood and body and Meursault sweat in front of the sun at the same time. Raymond can be symbolized as evil because he seduced him to drink wine just like Satan forced Christ to disobey God's orders but he resurrected. Emmanuel's innocence can be regarded according to Biblical reference Isaiah; he is the opposite of Meursault.
Arabs at the same time can be regarded symbol of the universe in which man always asks questions and it disappoints and remain silent, these Arabs can be regarded as the glimpse of universe, he also resembles them with his mother because she also remains silent.
