Looks nothing more than what I'm doing in my various tools to convert legacy
languages source to html to colour nested parentheses, in essence:

colour[0] = 'red'
colour[1] = 'blue'
colour[2] = 'green'

cur_col = 0

and for the next colour: cur_col = (cur_col + 1) mod 3

[Sounds right. Keep in mind that this paper is from almost 50 years
ago, and the comments on the web site said it was trivial, written for
a conference where you needed to submit a paper to go, then he went
and decided it wasn't worth it. -John]
