To sterilize empty jars, put them right side up on the rack in a boiling-water canner. Fill the canner and jars with hot (not boiling) water to 1 inch above the tops of the jars. Boil 10 minutes at altitudes of less than 1,000 ft. At higher elevations, boil 1 additional minute for each additional 1,000 ft. elevation.
Analogous colors. From Wikipedia, the free encyclopedia. Analogous colors are groups of three colors that are next to each other on the color wheel, with one being the dominant color, which tends to be a primary or secondary color, and one on either side of the color. Red, red-orange, and red-violet are examples.
Understanding Color Contrast. It is easy to understand how color can create contrast. For example, complementary colors provide a high level of contrast. Complementary colors are colors that are located directly across from each other on the color wheel.Red and green, blue and orange, and purple and yellow are all examples of this. But when using complementary colors, we also have to consider value.Value is the darkness or lightness of color. Without contrast in value, the contrast created by complementary colors is counter-productive.ut when using complementary colors, we also have to consider value.
