Based on a practical understanding of phonology, we have color-coded some letters to facilitate the correct recitation of the holy Quran. This enabled us to classify these letters into three possible categories to enhance the reader's knowledge and remembering of Tajweed rules:
- The letters which requires expanded vocalization. We used red color to highlight these letters.
- The letters which are nasalized these letters are green in color.
- The dark blue color indicates the emphasis of the letter (R), the blue color indicates the unrest letters-echoing sound- (qualquala)
- While the letters which are written but are not vocalized. These letters are gray in color.
The reader will get used to reciting the Quran by using colors very easily. By engaging the eye, the reader will find him/herself applying 24 rules of Tajweed with ease and precision while his/her mind is left un-enganged to comprehend and understand the meaning of the holy Quran.
