Those lines are expressed using pixels and each of those pixels have a 
colour.

A segment detector could detect lines all over a picture, but it needs to 
be thresholded to lines significant enough. Lines that are too subtle have 
to be left out. In dark faces, or à contre-jour, how does Haar's algorithm 
figure out that lines inside of the face are more significant than those 
outside ?
