The great artist, Michelangelo, was born this day in 1475. When undertaking large-scale redecorating jobs like the ceiling of the Sistine Chapel, he knew how to use color effectively to achieve dramatic and breathtaking effects. However, most of us are far less talented and many are truly color-challenged. Here's a time-honored way to pick the right hues and tones. Knowing the color wheel can you help govern your home's overall look and feel. There are three primary colors; red, blue and yellow. Secondary colors are a mix of two primary colors. You make green by mixing blue and yellow. Tertiary colors are a mix of one primary color and one secondary color -- blue-green, for example. All other colors are derived by combining different amounts of primary colors and toning them with black and white. Other words to remember: "Hue," a range within a primary color, and "intensity," the degree of color. If you hope to create a masterpiece, you must first know the basics. And that's the On The House tip for today.
