UK TV News Twitter feeds with rainbow branding today:
Although it wasn't strictly rainbow branding - it was ITV Pride branding which recognises ITV's LGBT+ employees (including ITV News employees).
It's indeed not Strictly Rainbow branding, that's the wrong channel and there are no dancers or glitterballs to be seen.
As it is, it's clearly a rainbow.
