I'm mulling over the idea of purchasing a Tweed day jacket and waistcoat in green.

I have noticed that almost every website I visit has different greens listed.
If they are all real tweed I figure that they basically come from the same mills.
Just like most tartan wool come from the same basic 4 or 5 mills or so

Is there really a vast differences in the greens or just marketing words?

Forest, Highland, Dark, grounds keepers, lovat etc

How is one to know which colour to pick without having the swatches in had?
