In some ways, the term Manila or Manilla (another used spelling of Manila) has become synonymous with color. Manila paper is buff-colored and the un-dyed, natural, earthy look is ideal for any professional work. Manila fibers produce a buff-colored pulp which makes a brown shade of paper in its unbleached state, which became synonymous with brown envelopes and files in the 19th century. In some ways now, the smooth light brown-ish / yellow-ish color has been typically associated with Manila paper and therefore, the color has its unique identity. Manilla is often now used as a color description of brown shades like in paints.
