Help with colours

[Capt Troy Tempest]

I just purchased some emergency figures, and need help with colours.

First yellow high visibility yellow coat. What is best colour to use.
Second green for medical scrubs.
Third burgundy red colour for fireman uniform.

This figures are U.K. figures.
Thankyou for any help.

I think I would go with Green Stuff World's Blazing Yellow from their Opaque Colours range and GW's Orruk Flesh would be perfect for scrubs.
