[plt-scheme] SLaTeX question

When I process the following input file with pdf-slatex:

(+ (* 6 4) (- 3 2))

the parentheses are in green, the numbers are in black, the + and * are 
in blue. But the - is in green. Why? Thanks. --PR

(PS My twelve-year-old noticed this while being the audience for a 
practice lecture.)
