LIGHT: African violets are grown indoors. They like bright, but filtered, sunlight. Do not place in direct sun. They can also be grown under florescent lights. The lights are usually suspended 12 to 18 inches above the violet for 8 to 14 hours a day.
Purple and violet are similar, though purple is closer to red. In optics, there is an important difference; purple is a composite color made by combining red and blue, while violet is a spectral color, with its own wavelength on the visible spectrum of light.
