The Palladio door cross section as seen in the attached photo shows how the dye runs 3 mm deep into the skin. The advantages of this are that if the door was ever to be scraped the base colour would not come off. It would still remain green or red or whatever colour it was originally. It also guarantees no fading for years to come, so unlike a car that is sprayed the Palladio Composite door dye runs deep into the skin. So therefore it is not subject to chipping or fading from the sun UV rays that can cause damage to surfaces that have a spray coating as apposed to dye running right through the skin.
