Usually, I'll wear a striped tie. My favorite is from the UK....Soldier's Benevolent Fund. And I have a few other striped ties similar to the ones OC Richard has mentioned. On occasion, I'll not hesitate to wear a solid color tie. I have no problem with that. Tartan ties, well, I have two, but wear them non-kilted.

As for flashes, I have many colors in my drawer, but prefer red, blue, or green. Oh, and I do wear purple with my Isle of Skye kilt; and claret hose.
