need advice on color

[gristy]

6. yes, very good.

Thanks, procon. I googled and here's one of the first links that describes the 6 color schemes: https://learn.g2.com/color-schemes
And here's the couch I'm looking at:
https://www.la-z-boy.com/p/sofas/leighton-sofa/_/R-610653
with the color B166302 or C124191 (one can use the search button, next to "All Patterns" on the right, to bring up the couch in those colors)
I read online that the loveseat should be the same color as the sofa, and a nearby chair should be a different color to provide an interesting complement or contrast. Discovering the right color for that chair as well as for an area rug that pulls all this seating together is my goal right now.
