Wear Yellow for Seth: From firemen to Ashton Kutcher - all these people joined in

Seth LOVES the colour yellow (Picture: Youtube)

Friday 27th March was a sunshiny day all over the world, and it was nothing to do with the weather.

No, Friday 27th March was a sunshiny day, because the world came out and wore yellow as a way of sending love and support to this little guy, Seth Lane.

Five-year-old Seth loves Fireman Sam and the colour yellow. He also happens to have severe combined immune deficiency (SCID), which means that hes very ill indeed.

Seth is currently confined to a room in Newcastles Great North Childrens Hospital while he awaits a second bone marrow transplant, which is why his mum (who runs this blog called Our Little Hero) thought it would be nice for the world to come to Seth.

And today it did. Check this out

And the campaign stretched over the pond too.

The team at Good Morning America got involved

Even HRH got involved (well sort of)

Good job guys!
