In order to keep the public's eyes out of the way, those who run The True Self machines describe them as "Spa/Fashion Swiss Army Knifes" instead of their true purpose "Transformation Machines". As the name suggests it is the 6th generation, the reason is; the delicate "Wild Side" mind reader needed more work than expected, such as the ambition of that comes with anything experimental. Although to avoid possible meltdowns and bad press only the most mentally stable and well are allowed in.

Red Light = Occupied
Blue Light = Meltdown/Emergency
Green Light = Vacant

How does it work?
First, a body scanner is used so that the possible additional colors, stripes, etc. follow the body line of the user naturally. The "Wild Side" zaps the user's head and then taps into their subconscious, from there changes the user's appearance to match such desires.

Fun Fact: The 'True Self 6.0' concept is inspired by Draythix's "Temple of True Self" but I put a more modern and thorough spin on it.

P.S. If you want to use this concept in your art, all you need to do is give me credit.
