According to the prevailing theories of the settlement of the Americas, migrations of humans from Asia (in particular North Asia) to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The majority of experts agree that the earliest pre-modern human migration via Beringia took place at least 13,500 years ago, with disputed evidence that people had migrated into the Americas much earlier, up to 40,000 years ago. These early Paleo-Indians spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of creation myths.

The 19th century also saw the use of red in art to create specific emotions, not just to imitate nature. It saw the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."

What was the name of vincent van Gogh's brother?
Answer:
Theo
