In an interview with io9, Arrow showrunner Marc Guggenheim spoke about season 4 of the CW series.

'Arrow Is Done,' Stephen Amell Dishes About Season 4 Of The CW Series

Although Guggenheim was pretty tight-lipped about any spoilers he did let out that the next chapter will have a lighter tone. The executive producer suggested that the show had gone the dark route but they might lighten things some.

"It will take a lighter tone. That's pretty much the only thing I say without spoiling it," he said. "We've been working for about a month now in the writers' room, talking about season 4, and I think that one thing we all collectively understood was season 3 beginning with Sara's death, because it's the death of a major character on the show, it set a tone for the remainder of the season."

Guggenheim added that he was "not the least bit apologetic for that tone."

"I happen to like dark and I like the fact that Arrow is a pretty dark show particularly for a network show. That said, every year you want to mix things up and there was sort of a collective desire on all of our parts to try to inject a little bit more lightness into the show, a little bit more humor. It's not going to radically change. The show's still going to be the show but in terms of tone we're coming off a very very hard season for all of our characters. We wanted to try to mix it up a little bit."

The announcement of Arrow's renewal for a fourth season was made earlier this month.

The finale of season 3, entitled 'My Name is Oliver Queen,' of Arrow aired on May 13 on The CW.
