The skirting color we chose was a bust: too dark, and would fade and peel almost immediately (we were told). So our painter suggested we get crafty and mix the existing skirting color with the wall color to make a custom color, then we could get it matched at the paint store.
We tried mixing them both equally, it was a great-looking color, but too dark (colors 1 - 3). Adding the lightest trim color created a gray that was blue - which didn't go with our scheme at all. We tested custom colors until we got one that worked, the 7th one was a charm!
I can't even really tell you what colors are in here. I mixed the wall color (Benjamin Moore/Willow Creek) with the original trim color (Benjamin Moore/Wrought Iron), then threw in a little this and that from all the samples we bought. I don't think I could arrive on this color again if I tried, but I don't have to! The color has been immortalized on a greasy pizza box and the color-matching software program at the paint shop will mix it up.
