Stefan-Boltzmann law notes that the higher the temperature, the more luminous the body is, so such stars produce great amounts of visible light.  The hotter the star the shorter the wavelength it peaks at. A star that emits light across the entire visible spectrum would appear white. One that peaked beyond the visible would appear blue-white.  A cooler star may peak in the red part of the spectrum, or even in the infrared.
