However...maybe I am of a different mind now. While working on my Gripping Beast Arabs, I also decided to hit the lead mountain and paint this unit of Arab infantry from Essex. Colors and heraldry may have entered Europe through exposure to Muslim armies in Spain or the Near East, so uniformity of colors may be appropriate in this instance.
Essex is one of the older players in the historical miniature market and the figures are a bit dated. The posing is stiff, the hands are poorly formed and they are a bit "flat" which was a necessity in older casting tech. On the positive side, fabric folds and belt details are finely done and hold up alongside recent lines.
I like the look of a 15 man unit (two are not pictured) lined up in identical colors. A unit of identically painted Holy Order Crusaders might match against them nicely. The movement tray is from Litko and the printed flag was found at the DBA Fanaticus site: Flags and Banners for DBA
Bonus pic below is another easy conversion of a GB Arab head on a Wargames Factory Numidian body for a light skirmisher.
