Sweet, I'm inclined to agree. It's a desperately faint grey (but probably a shade darker than what I can at least see on my screen, who knows what the CRL team are expected to do after the colour has been through a camera lens and then onto a monitor....), I've seen some vests look a lot darker, but then some flight suits and vests look incredibly similar. The flightsuit pantone colour is up on the crl, which is awesome, they're just lacking the vest colour. My vest is definitely lighter than the recommended flight suit colour, but it's certainly easier to darken it than lighten it.
Will get Mum to make the vest and see what happens I suppose.
Onwards and upwards!
