It depends on what product you use (i.e. tanning booth, spray tan products such as DreamTan or pharmacy brands, etc.), how dark it is (i.e. light, medium, or dark re tanning booths), and also on your personal skin colour/tone (i.e. white, tanned, etc.) and melatonin levels (i.e. don't tan, tan in less than an hour in the sun, etc.). Usually it will just make an already golden individual darker, or one who tans easily the colour they might get after a few hours in the sun. Someone who does not tan or who is white may experience unattractive colouration on spray tanning.
