During their search for the dead unicorn in the Forbidden Forest in the 1991–1992 school year Rubeus Hagrid instructed Harry Potter, Hermione Granger, Neville Longbottom and Draco Malfoy to use red sparks if they were in trouble and green sparks if they have found the unicorn.
This spell may be related to Verdillious, which also produces green sparks. It is also possible that they are the same spell.
