Colour Doesn't Matter was painted by Darwin artist Megan Adams as a response to the racial abuse of her friend's Indigenous son, a Year 6 student.
"He's just the kindest, happy-go-lucky kid so it was really hard to see him so upset," Ms Adams said.
"Adam Goodes is a fantastic AFL player but he's also a great speaker, speaking against racism; the troubles he went through also related to experiences my friend's son had."
