EN 60204-1:2006+A1:2009 13.2.3 states " Where a circuit includes a
neutral conductor that is identified by color alone, the color used for
this conductor shall be BLUE. In order to avoid confusion with other
colors, it is recommended that an unsaturated blue be used, called here
"light blue" (see 3.2.2 of IEC 60446). "
It's only a recommendation, so can't be enforced. Discussing shades of
blue is not productive, because people with normal colour vision can
detect hundreds of shades, and some people can detect far more.
It's very unlikely that anyone is making wire coloured 'saturated blue'
anyway; that would require a special pigment and special process
control.
