One Direction have thanked their fans in Amsterdam for embracing their orange colour-themed concert.

The British hitmakers - comprising Harry Styles, Niall Horan, Zayn Malik, Louis Tomlinson and Liam Payne - recently informed fans that there would be a "strict dress code" of the bright hue at last night's show (May 3rd) for their concert at the Ziggo arena.

After the sold-out tour date, the boys took to Twitter to thank their fans for being ever-faithful.

Horan wrote on the social networking site: "Amsterdam u were unbelieveable tonight! Never heard noise like it ! And also #weturnedziggoorange ! Orange madness."

The Irish charmer added: "im 1000 percent sure we have the best fans in the world...the lengths you go to for us is incredible..we love u soo much ...no lies or poo (sic)."

Styles was also overwhelmed with the effort from One Direction's loyal fanbase.

He wrote: "Amsterdam... You were incredible. Thank you so much for having us!! You turned Orange. So did we (sic)," with an accompanying picture of the crowd taken from the stage.

Payne also thanked the band's followers after writing earlier in the day: "Happy orange day people of Amsterdam can't wait to see the crowd tonight see who got the memo aha (sic)."
