柏柏旗幟由三條橫條組成：上半部為藍色，象徵地中海；下半部為綠色，象徵塔馬茲加平原；下半部為黃色，象徵沙漠。在這些條紋之上疊加著字母「阿札 (雅茲) ⵥ」，象徵著提非納格文字 (伊馬齊根人的古老文字)，紅色代表鮮血和自由。

The Berber flag has an upper band of blue like the Mediterranean Sea, then a green band like the plains of Tamazgha, and finally a yellow band representing the desert. Upon these stripes is superimposed the letter Aza (yaz) ⵥ, symbolizing the tifinagh, ancient writing of Imazighen, in red, representing blood and freedom.
