Color-Coded Tajweed Explained

Guides › Color-Coded Tajweed Explained · Updated October 2026

Tajweed is the set of rules for pronouncing the Quran correctly: how each letter is articulated, when sounds are lengthened, merged, or nasalized, and where to pause. Learning these rules traditionally happens with a teacher, but a color-coded tajweed Mushaf is a helpful companion. It prints certain letters in different colors so that you can see, at a glance, where a particular rule applies. Our app Quran Color Tajweed + mp3 combines this kind of color-coded text with audio recitation.

Why colors help

When you read without color-coding, you need to recognize each rule from the letters around it. Color-coding gives a visual reminder: when you see a highlighted letter, you know to lengthen, nasalize, or soften it. This is especially useful for beginners, for children learning to read, and for adults who want to refresh their recitation.

Rules that are commonly highlighted

Different publishers use slightly different color schemes, so always check the color key (legend) in your Mushaf or app. The rules most commonly marked include:

• Madd (elongation) — vowels that are held for longer than normal, often shown in several shades according to how long they are held (for example two, four to five, or six counts).
• Ghunnah (nasalization) — the nasal sound produced with the letters noon and meem when they carry a shaddah, held for about two counts.
• Ikhfa' (concealment) — when a noon sakinah or tanween is followed by certain letters, the noon is partly hidden with a nasal sound.
• Idgham (merging) — when a noon sakinah or tanween merges into the following letter, with or without nasalization.
• Iqlab (conversion) — when a noon sakinah or tanween is followed by the letter ba', it is pronounced like a meem.
• Qalqalah (echo) — a slight bouncing sound on the letters qaf, ta', ba', jeem, and dal when they carry a sukoon.
• Silent letters — letters that are written but not pronounced are often printed in a light grey.

Combining color with audio

Colors show where a rule applies, but listening shows how it should sound. A good routine is to:

1. Listen to a short passage by a precise reciter while following the colored text.
2. Pause after each verse and repeat it yourself, paying attention to the highlighted letters.
3. Replay the verse to compare your recitation with the reciter's.

Slow, measured murattal recitations are best for this. See our guide to choosing a Quran reciter for suggestions.

Limits of color-coding

A color-coded Mushaf is a learning aid, not a replacement for a teacher. Some aspects of tajweed — such as the exact place of articulation of each letter (makharij) and the qualities of letters (sifat) — are not shown by colors at all and are best learned by listening and receiving correction. If you can, recite to a qualified teacher regularly, and use the colors to support your practice between lessons.
