关于iphone内置铃声蓝调是来自哪一首英文歌

以前听过一次，忘记名字了。伴奏就是iphone内置铃声蓝调一直重复，然后是男声唱的(不知道算不算rap)，比较伤感。求帮助找回歌名

So don't be afraid to let them show
Your true colors
True colors are beautiful
Ooh,Like a rainbow

So sad eyes
Take courage
Oh I realize
If this world makes you crazy
And you've taken all you can bear
Just call me up
Because you know I'll be there
And I'll see your true colors
Shining through
I see your true colors
And that's why I love you
So don't be afraid to let them show
Just show your true colors
True colors
True colors
Shining through
I see your true colors
And that's why I love you
So don't be afraid to let them show
True colors
True colors are beautiful
like a rainbow
