  I consider whether we can significantly improve the Cardelli et al. (1989)
family of extinction laws using new data and techniques. There are six
different aspects that need to be treated: The use of monochromatic quantities,
the three different wavelength regimes (NIR, optical and UV), the sample, and
the photometric calibration. Excluding the behavior in the NIR and UV, I
discuss the other four aspects and propose a new family of extinction laws
derived from VLT/FLAMES and HST/WFC3 data.
