Surnames relating to color are relatively common in Spanish, and in Catalan too. Examples: Blanco in Spanish and Blanc in Catalan, meaning White in English, Rojo in Spanish and Roig or Vermell in Catalan, meaning Red, Negro in Spanish and Negre in Catalan, meaning Black.
Colors vary in several different ways, including hue (shades of red, orange, yellow, green, blue, and violet), saturation, brightness, and gloss. Some color words are derived from the name of an object of that color, such as  orange  or  salmon , while others are abstract, like red.
