What colour was Edward the Engine in the "The Railway Series" made into the TV show "Thomas & Friends"?

"The Railway Series" is a set of British children’s books about a railway system located on the fictional Island of Sodor. There are 42 books in the series, the first being published in 1945. Twenty-six were written by the Rev. Wilbert Awdry, up to 1972. A further 16 were written by his son, Christopher Awdry; 14 between 1983 and 1996, and two more in 2007 and 2011.

Characters and stories from the books formed the basis of the children's television series "Thomas & Friends". Audio adaptations of "The Railway Series" have been recorded at various times under the title "The Railway Stories".

Edward the Blue Engine (No. 2) is a 4-4-0 ex-Furness Railway K2 class locomotive. He is the first character to appear in "The Railway Series". He is painted blue with red stripes. He was built in 1896 and arrived on Sodor in 1915 on loan with other engines to assist in the Railway's construction. As a 'shy steamer', he was not required back when the construction work was finished, and was formally sold to the NWR in 1921.
