Which of the following Arab countries does NOT have a flag containing only Pan-Arab colours?

Qatar is the Arab country that does not have a flag containing only pan-Arab colors. While most Arab countries' flags have a combination of the pan-Arab colors - red, black, white, and green - Qatar's flag stands out as it features a maroon color. The maroon color on the Qatari flag represents the historical significance of the country and is, therefore, distinct from the traditional pan-Arab colors.
