لون هالقميص ابيض، بس لون الشنطة احمر.

In Arabic, the verb to be is usually not expressed in the present tense.

So:

• لون هالقميص ابيض = The color of this shirt is white
• literally: color this-shirt white

This is completely normal in Levantine and in Arabic generally.
If you wanted a past or future meaning, then a verb would appear:

• كان لون هالقميص ابيض = The color of this shirt was white

It literally means the color of this shirt.

This is an idafa structure, which is how Arabic often expresses of or possession:

• لون = color
• هالقميص = this shirt

So:

• لون هالقميص = the shirt’s color / the color of this shirt

Arabic usually does not use a separate word for of here.

هال is a very common Levantine way to say this before a noun.

So:

• هالقميص = this shirt
• literally: this-the-shirt

In Levantine, هال + noun is extremely common:

• هالبيت = this house
• هالبنت = this girl
• هالشنطة = this bag

It is more colloquial than the more formal-style هذا القميص.

Because this is an idafa construction.

In an idafa:

• the first noun usually does not take الـ
• the whole phrase becomes definite because of the second noun

So:

• لون الشنطة = the color of the bag
• not اللون الشنطة

Likewise:

• لون هالقميص = the color of this shirt

Since هالقميص is definite (this shirt), the whole phrase is definite.

Yes, you could say it more briefly, but repeating لون makes the contrast very clear:

• لون هالقميص ابيض، بس لون الشنطة احمر
• The color of this shirt is white, but the color of the bag is red

Repeating لون sounds explicit and balanced.

A shorter version would be:

• هالقميص ابيض، بس الشنطة حمرا

That means:

• This shirt is white, but the bag is red

Both are natural, but the original sentence focuses specifically on color.

Because احمر is describing لون, not الشنطة.

Look at the structure:

• لون الشنطة احمر
• The color of the bag is red

The word being described is لون (color), and لون is masculine, so the adjective is masculine:

• ابيض
• احمر

If you described the bag itself, then the adjective would agree with شنطة, which is feminine:

• الشنطة حمرا = The bag is red

So:

• لون الشنطة احمر = adjective matches لون
• الشنطة حمرا = adjective matches الشنطة

This is a very common point of confusion, and it is important.

Yes, absolutely. That is a very natural Levantine sentence.

Compare:

• لون هالقميص ابيض، بس لون الشنطة احمر

  • focuses on the color of each item

• هالقميص أبيض، بس الشنطة حمرا

  • more direct: This shirt is white, but the bag is red

The second version is often more everyday and conversational.

Here بس means but.

So:

• ... بس ... = ... but ...

In Levantine, بس is very common and can have more than one meaning depending on context. It can also mean only / just in other sentences.

Examples:

• بدي قهوة بس بدون سكر

  • I want coffee, but without sugar

• بدي قهوة بس

  • I only want coffee

So in your sentence, the meaning is clearly but.

A common Levantine pronunciation is roughly:

• ابيض = abyaḍ / abyad
• احمر = aḥmar

In everyday speech, the feminine forms are often heard too when the noun is feminine:

• بيضا = white (feminine)
• حمرا = red (feminine)

So you may hear:

• القميص أبيض
• الشنطة حمرا

Also, in informal writing, people often write:

• ابيض instead of أبيض
• احمر instead of أحمر

That is just a spelling simplification in casual writing.

It is understandable and natural, but it sits a bit between colloquial and neutral/formal style.

What feels clearly Levantine:

• هالقميص
• بس

What feels a little less colloquial than the most casual speech:

• using لون ... لون ...
• using masculine color adjectives because they refer to لون

A very everyday Levantine version might be:

• هالقميص أبيض، بس الشنطة حمرا

So the original sentence is fine, but a speaker in casual conversation may often choose the shorter version.

الشنطة means the bag because of الـ.

So:

• شنطة = a bag / bag
• الشنطة = the bag

In your sentence:

• لون الشنطة احمر = The color of the bag is red

If you wanted a bag, you could say:

• لون شنطة احمر = The color of a bag is red

But in real conversation, Arabic often prefers a fuller context, because bare indefinite nouns can sound less specific than in English.

A very useful pattern is:

• لون + noun + adjective
• the color of + noun + is + adjective

Examples:

• لون السيارة أزرق

  • The color of the car is blue

• لون البيت أبيض

  • The color of the house is white

• لون هالوردة أحمر

  • The color of this flower is red

This is a good pattern when you want to talk specifically about color, rather than just describing the object directly.
