It is of His Glory's gifts upon us that He made His Qur'an easy to comprehend. It's words were written in a simple way, during the age of the prophet Mohammed (Allah bless and give him peace). Its letters were vowelized during the days of Al-Imam Ali (May Allah honor him). Dots were placed on the letters which resemble each other, during the days of Caliph Abdul Malek Ibn Marwan. Now Allah has gifted us with the idea of symbolizing some letters which are subject to recitation in His Noble Book, by using colors to indicate the rules of recitation and their timing in order to facilitate the recitation of the noble Qur'an. Glory's words: "Intone the Qur'an slowly and distinctly."
