When I do wear flashes they are usually a solid color, and usually in "other." These are my homemade knitted ones. Due to health one of my legs varies in size enough that these softer ones are much more comfortable.

When buying/making a nice kilt I like having the tartan flashes...they can come in handy for those rare (for me) formal occasions.

I have even been known to wear tartan flashes with a solid color kilt. It's kinda fun to turn things upside down now and then.
