You could consider 'Concord' as about neutral in the Vibrant purples. It's a basic purple shade, and so is very versatile. The blue undertones are pretty, and there is a good amount of blue in the formula. And remember, all the Vibrant purples have only two of the three primaries in them, so they are nice and bright, without the third primary to soften them.
NOTE: In general, use the individual color image as your guide. I have devoted many, many hours to adjusting the images to match the actual wool color, but the usual disclaimers (about colors appearing different on different monitors) apply.
HOW TO ORDER
The standard minimum size available at Ram in the Thicket is a 3" X 18" increment, and each of those represents one "item". So from each listing, order the total number of increments of that color you would like. If you order more than one 'item' of any color, I will send it out as one large piece.
