In loose, flowing clothing, the air around the body flows freely and cools more readily. On severely hot days, we might be uncomfortable as is everyone else. Muslims are to dress in modest clothing, without attracting attention to oneself. For this reason, many Muslims choose earth-tone colors such as green, blue, gray, as well as the usual black and white. Beyond this, there are no specific meanings behind the choice of color.
Some colors are more common in certain parts of the world, based on local tradition.
While Islam outlines a code of modesty, it does not command a certain style, color, or fabric. The range of clothing you find among Muslims is a sign of the great diversity among the Muslim community. It is generally understood that men are not to expose the area of their body from the navel to the knee. However, many Muslim men would feel shy to expose a bare chest or bare legs in public. As with women, men are not to wear clothing that is tight or see-through.
