Note that "couleur café" is not the standard way of saying brown in French. We have the words "marron" (which is literally the colour of a chestnut - in French is it obvious whether it is the colour that comes from the fruit or the reverse) and "brun" (same origin as brown) which are equivalent, one or the other being preferred depending on the region. "Couleur café" is most often used to refer to skin colour, and mostly for poetic or literary purposes.
