We consider numerical models of accretion disks and boundary layers (BLs) around white dwarfs in cataclysmic variables (CVs). Our models include the effects of the radial viscous force and are created using the realistic OPAL opacities. We present the composite continuum spectrum of our ``fiducial'' BL model, which is hot and close to the primary and is a strong emitter of soft X-rays. We examine the effects on the structure of the BL of variations in the model parameters: the mass accretion rate M, stellar mass M* and radius R*, stellar rotation rate Ω*, and viscosity parameter α. Finally, the ultraviolet colors of the models are computed for a range of system parameters and compared with the UV colors of observed CVs. We find that our models are consistent with the observed colors.
