I have a German flag on my left arm. The black and red look great. The trouble is the yellow stripe. I have been back to get it gone over twice but it still wont take. I worry due to me wanting to get other work with yellow in them.
we would need to see it, probably the shade of yellow being used doesnt work well with your skin tone,
certain colors dont show well thru our skin,
possibly you will just be able to switch ink brand and shade and have success
