Question: Extract the answer to the question from the following context. Question: Why did people immigrate to Portugal? Context: Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and/or personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975. By 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants.

Question: Extract the answer to the question from the following context. Question: To what substance did Ancient Egyptians add alizarin to make a red paint? Context: But, like many colors, it also had a negative association, with heat, destruction and evil. A prayer to god Isis said: "Oh Isis, protect me from all things evil and red." The ancient Egyptians began manufacturing pigments in about 4000 BC. Red ochre was widely used as a pigment for wall paintings, particularly as the skin color of men. An ivory painter's palette found inside the tomb of King Tutankhamun had small compartments with pigments of red ochre and five other colors. The Egyptians used the root of the rubia, or madder plant, to make a dye, later known as alizarin, and also used it to color white power to use as a pigment, which became known as madder lake, alizarin or alizarin crimson.
Answer:
white power
