Stealth Ink is a colourless liquid and looks just like pure water. The magic itself is in reaction with the UV rays. 

When there's no light the tag you leave remains colourless and perfectly invisible until the first touch of the sunshine. When sunshine hits, it appears almost immediately. In the underground and such spots the Stealth Ink takes more time to appear and often won't darken into as dark a shade as in direct sunshine. Nevertheless, the final shade will range from dark brown to black, depending on the UV exposure.
