question: Red is the color at the end of the spectrum of visible light next to orange and opposite violet. Red color has a predominant light wavelength of roughly 620740 nanometres. Red is one of the additive primary colors of visible light, along with green and blue, which in Red Green Blue (RGB) color systems are combined to create all the colors on a computer monitor or television screen. Red is also one of the subtractive primary colors, along with yellow and blue, of the RYB color space and traditional color wheel used by painters and artists.

In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.

question: Wide awake in Aunt Bet's Southern house, Annie Van Lew shivered at the sounds of distant guns. It was bad enough that America was at war, but the young Virginia girl was not used to battles being fought this close. _ .Annie sat up in bed and listened.Had a stranger broken in? Earlier, the family had heard that captured officers recently escaped from a prison nearby.

Quietly opening her bedroom door, Annie walked out. A figure in a black gown was walking down the hall. It was Aunt Bet, carrying a candle in one hand and a plate of fried chicken in the other.

Annie followed her aunt to a stairway at the far end of the house. Aunt Bet climbed to the top, and opened a door leading to the attic . Annie followed closely behind.

In the attic, Aunt Bet stopped at a chest of drawers, moved it aside, and felt along the wall behind it. Slowly a door sprang open, revealing a hidden room. A thin man stepped out of the opening. As Aunt Bet handed him the plate of food, the young man saw Annie in the doorway and froze.

Desperately shaking her head "no", the girl raised one finger to her lips. The officer understood and shifted his look. Quickly Annie went back downstairs and hid, waiting until after Aunt Bet left to return. Back inside the attic,Annie called softly to the man inside, who told her where to find the hidden spring.

Soon the young officer stood in the open doorway. A small candle burned on a table behind him and, in its soft light, Annie studied his face. Clear eyes reflected the calm of one who faced death bravely.

Smiling, he said,"What trouble you should have gotten into if your aunt had turned around!" That night, Annie learned Aunt Bet was one of many daring Southerners whose hatred of slavery drove them to risk their lives by spying for the North. The girl chatted as she dared, wishing her new friend luck when he said he would leave at dawn.
