   The blue symbolizes the river Nile, with its delta to the sea, the green symbolises the good agricultural land along its banks, and the yellow represents the desert elsewhere. The symbol imposed over the top is that of Isis, an main Egyptian goddess.

By Thomas Robinson, based on Lower Egypt

   The yellow is the desert, the green the riverbank, and the blue the Nile, as in the flag for Lower Egypt, but the bent blue line represent the cataracts that occur on the upper nile. The red symbols again represent Isis.

   Herodot refers that the Egyptians called the desert 'Red Land' and the fertile strip along the bank of the Nile 'Black Land', and the Nile was the source of life for both kingdoms, and the most important common ground.
   In addition, the white stripe could be changed to another colour, and the addition of the symbol of the two kingdoms, the red and white crown, can be imposed over the top.
