Red, red, red. No messing, no nonsense, bright, red. It's not orangey, or pinkish. There is no blueness, or purple-ness or brick. Maybe a bit of scarlet.
NB not super wash!
Reminiscent of London buses, Valentine's hearts, alarm bells. And fire engines. And fresh blood.
This is the red for socks and bloomers for when you're out on your broomstick and it's cold up there.
And easy to spot from the ground (for when you're not in stealth mode).
