According to the Oxford dictionary, tango, as a word for a dance originated in the late 19th from Latin American Spanish possibly via an African word for to dance, and as a colour (a deep orange red) in the early 20th century by abbreviating tangerine (as in a Tangerine orange - an orange from Tanger, as Tangier was known). This use for a colour is a dated and informal British usage. Which explains the orange but not Mike's bright pink, which could be a translation error of course
