If I have tattoos on both arms, can I have color tattoos on the left and black and white tattoos on the right?

I have the same problem recently, but I have been observing foreign websites and found that some people have tattoos like this. I think the key is to look at the style, such as the old school in Europe and America or the new school. A unified style will have a good effect! I've been studying for a long time, and I'm going to do it alone. If you have a better suggestion, please share it with me! !
