There are three primary colors: red, blue and yellow. They are the hues from which all other colors are created. Any of these will make a huge decorative statement on its own, but can also act as a powerful accent. Mixing white with any of these primary colors will create a soft pastel. Red turns to pink, blue to baby blue and yellow to pale yellow. These shades of pastels frequently cover the exterior of cottages, giving them the laid-back look of the Florida Keys. Shake it up a bit by painting the balcony in the primary color that was muted for the rest of the exterior. For example, a pale pink cottage with a pure red balcony will have a bold design impact.
There are three secondary colors: green, orange and purple. These shades were created by combining two different primary colors. Blue and yellow produce green, red and yellow make orange, and blue and red create purple. Using a secondary shade as the main cottage color and a primary color to accent the balcony and trim will create a harmonious look. For example, paint the body of your cottage a light shade of purple. Because purple consists of blue and red, add white to one of those colors for pale blue or pink accents.
You're not limited to colors normally found on cottages or even to those you see in a paint store. Adding a neutral shade such as white, brown, gray or black to any paint color will change the hue enough to make your cottage stand out. Black added to green creates olive green, a perfect accent color. Brown added to orange creates a rust color.
Those same neutral shades that are added to another color to change the latter color's hue, also stand well on their own. A light gray cottage with white trim and balcony will emphasize the balcony feature. A white cottage with a balcony trimmed in black will do the same. Not only will neutral colors give your cottage a fresh look, but they'll hearken back to the days when all cottages were painted using neutral pigments.
