Can anyone tell me why people are concerned how dark or light the guide colour is on a spray tan? as this does not reflect the tan outcome? I have just had a spray tan and although the guide colour was a lot darker to what the outcome was, I wouldnt have wanted to leave the guide colour on for a few reasons, the main ones being i felt sticky all day and i had "tide" marks on my neck and my creases which made me feel i had to explain myself to people i saw that day saying i am not really this dirty, i have had a spray tan. So i have read on other threads about what colour the guide tan is and how much darker the developing tan is or vice versa and my question is .......... why would it matter? am i missing something? surely the only thing of importance is the tan that develops next day?
