Paint code?

Hello everyone,
I painted my defender about 18 months ago using a commercial coach enamel applied with a radiator roller from B and Q. Turned out extra well.
I'm looking to change the colour to one similar to the Heritage edition defenders currently on sale. I'm told it is Grasmere Green.
Does anyone know the colour code as I'm unsure how close I could get just using a colour chart.
I've painted the wheels according to the correct colour code and had a new set of Michelin 750 x 16's fitted.
The roof remains nice and white so the whole appearance should look good.


Thanks
