Style Secret: Cool ColorsWhen you think about an industrial color scheme, you probably envision gray, gray and gray, with a little black and white thrown in for kicks. And while it's true that the range of colors in this style tends to be narrower than in others, there's wiggle room in the palette — as long as you don't overdo it. Start with a background of neutrals that have cool undertones, and then you could bring in a measured dose of citron, tangerine, fuchsia or another saturated hue. Or go dark and moody, as in this bathroom: indigo, plum, moss. Smart strategy: Even if you decide to stick mostly with grays, vary the shades — some light, some deep, some in the middle — to keep the space from feeling one-dimensional. Because of the emphasis on materials such as concrete, corrugated metal and perhaps a smidgen of rust, industrial style usually has built-in texture to break up the monochromatic palette. But if a room feels flat, consider adding a few more tactile elements to lend depth.
