I agree with the general tenor of the foregoing. I also remember what a hassle it was to choose wwedding colors in the first place, and then deal with the choice.

1. Find out what stock tartans you can claim a connection to. The color balance to the images on Loch Carron is very good, though it helps to cover the black background with some neutral colored shades held up to my computer monitor.

2. It is the bride's day, so you will have to be gentle, especially if the bridesmaid's dresses are already ordered/chosen.

3. What we did for mine (green and cream) was order my stock green clan tartan, did what we could to coordinate that green in the bridesmaids dresses and then put cream sashes on the bridesmaids to co-ordinate with the bride's dress. All the boquets were yellow and red, so I wore claret hose with yellow flashes. The party, I think, looked organized and coordinated with out looking upholstered. I would offer pictures, but my wedding was recent enough we don't have them back from the photographer yet.

4. When in doubt, it is the bride's day, not anyone else's.
