You seem to be referring to Elvis Presley and his favourite colour. There was a bit of a speculation that the favourite colour of Elvis was pink, but publicly, Elvis has never agreed about that. It seems that his favourite colour would be blue. There are two reasons why. One reason could be he has written many songs which contain the word 'blue' in it, such as 'Blue Suede Shoes', 'Blue Christmas' and 'Blue Moon'. Many artists such as Gillian Welch and Jimmy Buffet have sung a song about Elvis. The name of the song is 'Elvis Presley Blues'. So I believe Elvis' favourite colour would be blue.
