We present a quantitative investigation of the optical depth through spiral disks using BVRIJHK colors of 15 highly inclined Sab-Sc spirals and new models for radiative transfer in stellar disks. ... Preliminary comparisons of the observed optical and near-infrared (NIR) color gradients across galaxy dust lanes with predictions from radiative transfer models with slab and spherical shapes underscore the need for these realistic exponential disk geometries. ...
