I have tweed Argylls in lovat green and charcoal, and the charcoal goes with almost any colour tartan kilt, whereas the lovat green is rather more limited - green and red tartans do well, but many others are non-starters!

In your case, Seamus, Black Stewart will be perfect with charcoal tweed - black and grey go well together. Both your shirt and your tie should be unpatterned. A white shirt does well for all situations from very casual to very formal and, with Black Stewart, a plain red woollen tie would be perfect.
