French Colonial Infantry

I thought you might like to see one of the latest painting projects that I plan to undertake. There is a new line of 28mm minitures called "Askari Miniatures" that are very nice quality and very well priced. I saw a painted unit of French Foreign Legionnaires (FFL) on display at the Cold Wars convention and decided that I had to have them. I also grabbed a bag of tiralluers algeriens to use as French colonial allies. I thought they would be a colorful addition to the table top. So, the problem is finding information on how to paint them. I don't have any books with color plates on the FFL and the internet sources are rather sparse. The first picture is about all I have found so far. I get the impression that the tiralluers algeriens normally wore blue over blue unlike the zouaves that wore blue over red. I am also assuming that it is not a very dark blue either. I also see that the Askari Miniature chaps painted theirs blue over white! (second picture) Maybe there were variations from regiment to regiment? If anyone knows, please leave a comment.
