i think that algeria first colour is green , ane the secend is the whit one ,, :)
Maybe in the past was as you say, but right now the white kit is presented as the home (first choice) and the green one the away (second choice). Also the home kits for the African teams made by Puma have on the left arm(shoulder) a watermark with something specific to the country (the desert fox for Algeria, the Sfinx for Egypt, the star for Ghana, the elephant for Ivory Coast and so on). The away kits have stripes (pinstripes, hoops).
Your shirt to Slovenija is wonderful! Congratulations!
