Faint
A tsunami and a couple fires run into each other. They cancel each other out completely, and the remainder left behind is a faint remnant of what was once there.
You go to see if you can find any remainder of the fire + tsunami battle. You can, but it's so faint.

Just like the tsunami and fire canceling each other out, leaving a faint remainder of what was, your tan (たん) is extremely faint as well.
Look at your skin. It has such a faint tint.
