Unfortunately, there is no quick fix here, as I have found out over time, and most recently in my persuit of County Galway tartan. The ONLY way to know the true colors is to get a swatch of fabric from the mill that will weave your tartan.

Yep, even in fly tying there is a color system that tells one what color of green to use as hackle, but in tartans.......we will have to wait.

That is why on a previous post I queried, then suggested, a simple automated way of seeing a tartan pleated to sett, and to stripe. Very simple, yet not available right now.

Steve, you are a computer guru......this could be your calling!
