Homer started painting with watercolors on a regular basis in 1873 during a summer stay in Gloucester, Massachusetts. From the beginning, his technique was natural, fluid and confident, demonstrating his innate talent for a difficult medium. His impact would be revolutionary. Here, again, the critics were puzzled at first, "A child with an ink bottle could not have done worse." Another critic said that Homer "made a sudden and desperate plunge into water color painting". But his watercolors proved popular and enduring, and sold more readily, improving his financial condition considerably. They varied from highly detailed (Blackboard – 1877) to broadly impressionistic (Schooner at Sunset – 1880). Some watercolors were made as preparatory sketches for oil paintings (as for "Breezing Up") and some as finished works in themselves. Thereafter, he seldom traveled without paper, brushes and water based paints.
Keep in mind that color can impact the way a room appears in many ways. Light colors may help brighten a darker space. Cool colors will recede visually from the eye, and make a small space appear bigger. Warm colors contract visually, which can make larger spaces appear smaller or more cozy. Combining cool and warm tones in one room - like with accent walls - can visually change the shape of a room, making rectangles look more like squares.
The right paint stroke to use in interior painting is highly debatable. It's not a talent as much as a skill that is learned through practice. Many experts paint in a “W” pattern when using foam rollers, but others simply roll up and down then sideways with either brushes or rollers. The motion isn’t as important as making sure that the application is even and drip-free across the entire area. However, technique is important when you're covering over wall repairs.
