Whether you’re buying or selling a home, picking paint colors can be tricky.  A good paint job inside and out reflects one’s own style and taste, and can truly improve your property.

Paint has remodeling power when you use it to emphasize a room’s best features or play down the flaws.

Every home suffers a few negatives, but not every solution requires pricey structural changes. Paint is an often-overlooked, low-cost remodeler’s remedy for common complaints with interiors, offering the chameleon-like ability to lighten, warm, enlarge, erase, or attract attention.

“Paint is a powerful tool that can enhance the architectural character and intent of space,” says Minneapolis architect Petra Schwartze of TEA2 Architects. “As you choose your paint, think about what the experience in the room should be.”

More Schwartze advice:

• Always sample paint colors on a few walls. Don’t be shy about painting a few large swaths on walls and trim to consider the effect of natural and artificial lighting. Add samples to opposite sides of a room to judge the paint color from different angles.
• Check the space with the samples in place and watch how the paint color changes at different times of the day.
• Evaluate your reaction to the proposed colors: Does the space feel cozy or is the openness enhanced?

How to Enlarge Space with Color

Painting walls white, cream, pastels, or cool colors (tinged with blue or green) creates the illusion of more space by reflecting light. Paint trim similar to walls (or use white on trim) to ensure a seamless appearance that visually expands space.

In addition, using white or light colors on walls lifts the ceiling; darker shades can have a similar effect if you select a high-gloss paint sheen, which reflects light and enhances space.

Use a monochromatic scheme to amplify the dimensions of a room. Select furnishings in one color and paint walls and trim to match. Lack of contrast makes a room seem more spacious.

Make walls appear taller by extending wall color onto the ceiling. Create a 6- to 12-inch-wide border of wall color on the entire ceiling perimeter, or wherever walls meet the ceiling.

Vertical and horizontal stripes of alternating color can make a room grand. Although vertical stripes enhance room height by drawing the eye upward, horizontal stripes lure your gaze around the perimeter, making walls seem further away. Use similar light colors for low-contrast stripes, and your room will look even larger.

Creating Intimacy

When a space feels cavernous, draw walls inward and make it cozy with warm colors (red-tinged) because darker hues absorb light. Similarly, a dark or warm color overhead (in a flat finish) helps make rooms with high or vaulted ceilings less voluminous.

Give Peace a Chance

The right paint choice can lend tranquility to a bathroom, master suite, or other quiet, personal space. A palette of soft, understated color or muted tones help you instill a calming atmosphere. Some good choices include pale lavenders, light grays or greens, and wispy blues.

Define Your Room Assets

Call out notable features in a room with paint. Dress crown moldings and other trims in white to make them pop against walls with color. Make a fireplace or other feature a focal point by painting it a color that contrasts with walls.

“Using a higher sheen of paint on woodwork, such as baseboards and door or window casings,” says Schwartze, “creates a crisp edge and clear transition from the wall to the trim.”

Hide Flaws

Not everything should stand out in a space. Using a low-contrast palette is a good way to hide unappealing elements or flaws. Conduit, radiators, and other components painted the same color as the wall will seem to disappear.

Selecting low-sheen or flat paint colors also helps hide flaws. Unless walls are smooth, avoid using high-gloss paint because it reflects light and calls attention to an uneven surface.

What’s the Cost?

As a DIY job, painting a 12-foot-by-12-foot space costs about $150, including paint, primer, brushes, drop cloths, and other painting tools and supplies. A professionally painted room using high-quality, brand-name paint costs $200 to $400.
