The relation between visual surface brightness and (b-y)₀ color index is constructed for eclipsing binaries with Hipparcos parallaxes and photometry in the Strömgren four-color ubvy system. The relation is consistent with the Popper relation derived for stars with angular diameters obtained mainly from interferometry or from the lunar occultation method. It is shown that the Lutz-Kelker correction to magnitudes is in this case negligible.
