Tattoos are perfect artworks and maybe after some time you get really exhausted with looking at the same ones every day. You may take this as an opportunity to dazzle up your skin and add new colors because the previous color and the one that you will apply now will mix to give out a new shade. So, here are some guidelines and ideas, you can look up to when you need a cover up:
YOU CAN ALWAYS THINK OF PITCH BLACK.
Black is the most effective color when you want a cover up and you can also make it look entirely new because it will conceal whatever you had and it can be extremely elaborate and beautiful.
INCORPORATE OLD DESIGNS.
Putting the tattoos you had already had can give away nice results because you have to make sure the recent one has to be 30% larger than what you had or you could just re-work it and add illusions and create contrast and flourishing designs and develop it further.
You might love the design and still disapprove of the color. So, you can simply stick to the previous designs and experiment with shades and change to darker one, probably.
MAKE IT COMPLEX.
The more elements and fine details you add, the better the cover up turns out. For instance, you can add variegations on the leaves and add swirls of hair and make sure, you use dark colors.
Whatever be it, even the faded and crappy tattoos that you had once sported, are a part of your stories and considering that it has a lot of changes, we should splash some on these too. Just find the correct tattoo artist to approach and take whatever time you need.
Hope it goes well.
