Can you lighten a tattoo with white ink?

Hi ladies. This might be a stupid question but I recently got a tattoo that seemed great in my head but didn’t come out the same on my skin. The background is a lot darker than I initially wanted. It’s now healed and I want to do something about it. I’m not particularly looking to laser it off as I don’t dislike it, just the turquoise colour is too dark for my preference.

Is it possible to go over the background with white ink or blue ink mixed with white to make it lighter?

Thanks 😊
