Wednesbury's Clock Tower joined the likes of Canada's Niagara Falls, and Blackpool Tower, in raising awareness of baby Azaylia's brain tumour, which cannot be treated.
Azaylia, who is eight-months-old, is the daughter of former Coventry City player Ashley Cain and partner Safiyya Vorajee, who live in Nuneaton, north Warwickshire.
The light display in Wednesbury on Thursday night was carried out by Paul James Promotions.
Explaining the event, Wednesbury North councillor Elaine Costigan said: "I was being asked lots of question last Thursday about this child who is sadly dying of leukaemia, with people inboxing me saying is there no way we can do anything about it in Wednesbury.
"I thought if I go to Oldbury [Sandwell Council], it will take weeks and weeks, so I inboxed John Kennett [a photographer], saying 'do you think this is a possibility?'
"Within two hours, it was all organised, John got some team he knew to light up [the tower].
"Everything was going orange, even Niagara Falls that night was orange. We were the only town in Sandwell to do anything, good old Wednesbury.
"It was so lovely how quickly the community got together to sort this out, it was wonderful.
"The feedback, on everywhere, Facebook and Twitter, was just incredible. I know Merry Hill was lit up as well, and somewhere in Birmingham."
