Your nails are just stained from the nail polish. To make them return to the natural color, gently file them and after this, take a buffer (you can buy a file/buffer that's called 3-in-one, it's one piece that has (#1 file and the other side of it is half smooth #2, other's is smoother#3.)
After filing using#1 the step above. Use #2 to smoothen the surface of each nails. Followed this by the #3 smoothest side ---buff faster and very lightly press on to your nails.When done, wash both hands. DO NOT SOAK in BLEACH as this will harm your skin esp. sensitive skin will be dry. Just get a cotton, wet w/ regular peroxide. Apply this on top of your nails only just like applying nail polish remover. Press the cotton till whole nail is wet and leave on for 30 sec. each nails to soak. This will maintain your nails to be white as always. Make sure everytime you put nail polish, use base coat then the colored polish, then top coat. If your nails always turn yellow or darker, it could be because you're taking medication or you should see a specialist as this could be a sign of something else. Goodluck.
