Tattoo Colors after healing
The skin is often represented as 3 different layers, the epidermis (the upper most layer), the dermis (middle layer) where the ink should be deposited, and the hipodermis (lower layer). The epidermis is changing constantly and all the cells in the epidermis are renewed after some time. The main point is that ink can not be permanent in the epidermis, it has to be deposited in the layer below, this is where it stays.
Is the ink in the dermis always permanent?
No of course not, nothing is permanent, but the better the technique, the better the aftercare and the better the ink is the better it will stay in the skin! Let’s assume that the tattoo is done with proper tattoo techniques and the healing of the tattoo art is taken care of properly, then the biggest factor playing a role is going to be the quality of ink. There are many factors that will play a role in the permanence of the ink as well.
The body naturally reacts to remove all foreign objects from the body by sending special cells to capture the ink particles and carry them out through the capillary system. The ink Particles that remain in the dermis are those that are too large for the body to dispose of. Most inks vary quite a lot in particle size and this can often lead to small changes already during the healing of the tattoo. So make sure to use good quality inks for a long lasting vivid tattoo.
Many pigments will react to UV light by breaking down into smaller particles, which the body's cells can then absorb and get rid of. This will directly affect the tattoo.
Depending on the mixture of pigments in your ink the actual pigment can change quite drastically after exposures to strong UV light. This is to say that the actual color of the pigment can change when exposed to UV light.

Exposure to sunlight will not only affect the pigment but also the way it is seen
As Melanin (the skin's natural pigment) most often is located in the upper skin layer it is acting as a brown filter on top of the tattoo ink, this means it will automatically make the tattoo look more faded than it would naturally do (think about it like adding a filter to your picture on Instagram). So make sure to protect your art by protecting yourself from strong and direct sunlight!

None of the above matters if the initial healing is not taken care of
It is crucial to ensure a good initial heal as this is the most important part of the healing. A bad initial heal can in the worst cases lead to prolonged pain, infections, scabbing or color loss to name a few. In some cases it can even be a combination of all of the above.
