This one is for Jo Soss, taken right off the stairway wall of a recently sold home in Seattle.
The color was really a Brown Sugar like the one below from Benjamin Moore
But the lighting from the bottom to the top of the staircase gave it that variated pattern and color tone.
A slightly lighter version of Seville Brown below would give you the mid-tone
Here's a trick I use all the time and recommend to my clients. Instead of playing with color swatches to do tone on tone, buy the darker color like Seville Brown. Do one wall, usually the short wall or an alcove or the angled wall with a high ceiling.
Then mix the same color into white to do the rest of the room. That way the tone is identical, but the room isn't too dark all over. No guessing "is this the right tone" if you make two or three paint colors using the darkest color mixed into white. Make sure you put some aside for touch up paint in a glass jar though...cause you'll never get the exact same color match if you mix it yourself.
