In the Geneva photometry a box around a so-called 'central star' is defined as the set of stars having colors or parameters in the vicinity of the central star. Colors deduced from stellar model atmospheres may also be used as a substitute of the central star. The first aim of this paper is to give the general definitions of photometric boxes. Then the statement 'Two stars with almost the same colors (parameters) have almost the same physical properties' is examined both empirically and theoretically for some regions in the HR diagram. The ability of the Geneva photometry to provide accurate calibrations for B stars and F, G, and K dwarfs is confirmed. However, badly known reddening may deteriorate estimates of temperature and/or luminosity for A-type stars and for cool giants and supergiants.
