Preparing to paint some wood with Benjamin Moore's "Subtle", I was troubled to find that there was a can of Cameo White next to the plastic container holding what I had thought was Subtle. I found the quart can of Subtle, held it and the Cameo White quart next to each other, and could not distinguish the color of the paint smears on their sides. Either, held up next to the wood already painted, looked a plausible source. It then occurred to me that where intuition failed, analysis might serve; specially mixed cans from the Benjamin Moore stores have a sticker on the side that gives the components. The mix proved to be the same for that base, namely 5.25 OY, .25 BK, .5 each OG and GY. And on the Benjamin Moore web site, the suggested matches for each are "Elemental" and "Mississipi Mud".
Evidently the naming of paints is as special an art as the mixing of them. The color, call it what you will, strikes me as a beige or putty or light tan.
