Abstract We show that the lines of every arrangement of n lines in the plane can be colored with O( n/ log n) colors such that no face of the arrangement is monochromatic. This improves a bound of Bose et al. by a Θ( √ log n) factor. Any further improvement on this bound would also improve the best known lower bound on the following problem of Erdős: estimate the maximum number of points in general position within a set of n points containing no four collinear points
