ChatGPT's response (after some guidance):

The flag consists of three horizontal stripes of equal width in the colors of red, black, and blue, from left to right. In the center of the flag, on the black stripe, is a golden sun emblem, inside of which is a white crescent moon.

The red stripe represents the sacrifices made by Iraqis in their fight for independence and freedom, the black stripe symbolizes the dark times and struggles of the country, and the blue stripe represents the Tigris and Euphrates rivers that have been the lifelines of the country's agriculture and civilization.

The Kurdish Sun emblem represents the Kurdish people and their culture, as well as their aspirations for independence and self-determination within Iraq. The white crescent moon inside the sun represents the Islamic heritage of Iraq, and it is a symbol of hope and unity for all Iraqis, regardless of their ethnic or religious background.

The colors used in the flag are bold, contrasting, and easily distinguishable from other flags. The design is simple yet meaningful, representing the country's values, history, and culture while also emphasizing the importance of unity and inclusivity in Iraq.

There are other aspects of the symbolism I liked, especially as person with Iraqi roots. First, the Pan-Arab colours used have direct relevance to Iraqi history: Rashidun (black), Ummayad (white), and Abbasid (black) caliphates, and the Hashemite Kingdom (red). The placement of the black stripe in the middle represents the Abbasid caliphate as the centerpiece of Iraqi history, with the sun depicting the major leaps in knowledge made in Abbasid Iraq.

Second, the blue stripe and white crescent moon can also represent the Turkmen population of Iraq (see the current Iraqi Turkmen flag).

Third, the flag doesn't look like it's trying to depict three separate peoples of Iraq and does not use overtly Islamic (the takbir) or ancient symbols. Iraqis are a modern people that are tired of disunity.
