  colors2 = %w[cyan   forest green  burnt\x20umber]

Escaping the space ``\ `` might be nicer, but escaping an invisible
character is problematic (see the problems with the explict line
continuation character ``\``) and we may not be able to add any new
escape characters to the language. However a hex escape will do the

Compare that to:

colors2 = "cyan,forest green,burnt umber".split(',')

or, if you follow pep8-style commas:

colors2 = "cyan, forest green, burnt umber".split(', ')

This is one of the many cases where being able to specify the delimiter helps.
