"Moreno" is a Spanish word meaning "dark" or "dark complexed," as if to say "black" in terms of ethnicity. Similarly, "Rubio" is the word for "light" or "light complexed," as if to say "white."
"Negro" is the Spanish word for the color black, as in black coffee. It is not a racist term, as most people would have you believe. I have gotten unto arguments over speaking Spanish and using the word "negro" to refer to the color black, even though that's what it means.
