Reproduction colors vs. modern colors?

[Stan]

Hi Barb, here's my question.....What's the difference between reproduction colors, and modern colors? As I've been looking at tartans for a possible new kilt, on several tartans I see three choices in colors. Ancient, reproduction, and modern. On my monitor, the reproduction and modern look different, but not as "organic" as the ancient, which I know about.

I'm interested in understanding the difference between those two. Thanks for any help.
