Who's Afraid of Pink

Two of my most loved artists titled their works Who's Afraid of Red, Yellow and Blue? obviously playing off Edward Albee's Who's Afraid of Virginia Woolf?

1/ Barnett Newman's series of four very large paintings made between 1966 and 1968

2/ Robert Irwin's installation exploring the three primaries in three dimensions, 2006-07

In 2010 I wonder Who's Afraid of Pink and Who's Afraid of Yellow... I'm not.
