As I'm passionate about make-up and as a graduated (by this moment) beautician I'll try to answer these questions.
Arabic make-up varies in different countries. Since old times Arab women from Persian Gulf used kohl as decoration and protection for eyes. They grind special kind of a black stone to powder and applied it by a tiny (but much bigger than now) stick. The original dark colour of eyes was struck out by deep black eye liner which contrasted with the color of skin. It became the first distinct feature of Arab women make- up.
Men wrote thousands of beautiful poems about women's eyes that draw even more attention to this part of the face. With the time new colours were introduced in make up, yet black kohl is never forgotten. Most of all, khaliji make-up is famous for black kohl eyes. Retro style of khaliji eye-make up was limited to only one coloured eye-shadow (you can see as an example my earliest posts through "My make-up" tag). Nowadays there can be 120 colours in one pallete,100 make-up brand names in every moll. 2Drh cost eye-shadows are available everywhere. And then you just need to be a little bit creative to show all your talent and beauty on the next party or event. If you can’t apply make up yourself, there is always somebody who could do it for you - there are numerous beauty saloons all over the GCC. Or maybe there's some talanted lady among your relatives or friends. You just need to understand that the modern colorful khaleeji make up is a new look of the oldest cultural element.
Next pics belong to Dabyanyh beauty saloon. They are a wonderful example of the modern khaleeji special event make up. Very creative, very colorful and simply a work of Art.
