"Rutilant," which first appeared in English late in the 15th century, is used in English today to describe anything with a reddish or fiery glow, such as a sunset or flushed skin. It derives from the Latin "rutilus," meaning "ruddy," which is probably related to the Latin "ruber," meaning "red." "Ruber" itself is a direct ancestor of our word "rubella" (a disease named for the reddish color one's skin turns when afflicted with the condition) and "rubric" (which, among other things, can refer to a book or manuscript heading that is done or underlined in red). "Ruber" is also a distant relative of several English words for things that bear a reddish tone (including "russet," "rouge," and "ruby") and even of the word "red" itself.
