Matching Paint Colors Perfectly
DEAR TIM: I recently modified my living room curtains. This required patching numerous small holes. It's now time to match the flat wall paint adjacent to these patched areas.
I've never had luck in getting an exact color match from the paint store. The shades are close but you can always see the painted area.
Is there a way to match the color so I don't have to paint the entire room? Have you ever had success in matching colors in a situation like this? Vivian S., Cincinnati, OH
DEAR VIVIAN: Color matching has driven many people close to the edge of insanity. I recently met a frustrated woman in a paint store who said that she had over 50 quart cans of paint in her basement. These cans represented failed attempts at trying to perfectly match a wall color.
Color Matching Machines
Matching existing paint colors can be done. If you expect a paint store to do it for you, you need to bring in a clean sample of the paint color.
Paint stores have amazing optical scanners that can compute the needed pigments to match the sample you provide. Usually the sample needs to be about 1.5-inch square.
Minutes for a Match
A paint store with this equipment can give you a very close match within minutes. Often they'll mix a small quantity of paint, open the can, put a small amount of the new paint on your sample and use a blow dryer to see how well it matches.
The same color formula will render different shades of a color depending upon the sheen or gloss of the final paint. Keep that in mind!
If you decide to attempt it yourself, the process requires patience, excellent lighting, soap and water, and lots of luck.
I've had great success in the past. Recently I successfully matched a nine-year-old light beige color in a client's living room.
I did this by getting a slightly darker shade of beige than what was on the wall and I started to mix different small amounts of the paint with pure white paint until I got a perfect match. I was very lucky.
Interesting TIP: The color or hue of an object is actually generated by the light that's illuminating the object.
Sunlight produces all of the wave lengths or color possibilities that we can see with our naked eye. If you live in a place with low humidity, it's a cloud-free day and the sun is high in the sky, the colors you see of things outdoors are pretty much the true color of that object.
The Golden Hours
Let's say you're standing outside at noon on a cloud-free day at the Grand Canyon. You're blown away by the rocks and sky.
But you fall asleep and take a nap waking up just as the sun is about to set. All of a sudden the reds and oranges in the rock formations are far more vivid.
You're in what's known as the golden hour.
What's happening is the sun's light is now passing through lots of the atmosphere at such a low angle in the sky and the blue and green light rays of natural light are getting absorbed by the atmosphere. Only the reds, oranges and yellows of the color spectrum are making it through all the air and they enhance anything that's red, orange or yellow!
The same phenomenon happens at sunrise for about an hour.
Artificial light created by any type of light bulb has an almost impossible task. It's really hard to mimic Mother Nature.
Most light bulbs only put out part of the entire visible light spectrum.
As a result, an object viewed in natural sunlight outdoors at noon as we talked above can look very different when observed under artificial light (paint store fluorescent lights, living room lamps, etc.).
Parking-lot lights are good examples. Have you ever noticed how your car sometimes appears a very different color at night under harsh sodium vapor lights?
Many parking lot lights are sodium vapor or halogen. The trend now is to LED bulbs. All of these tend to create a very narrow band of color they produce.
Flat Paint Easiest
The sheen or gloss of paint also makes it very difficult to match colors. It's much easier to match flat colors than those with gloss.
High-gloss paints are very unforgiving. It's almost impossible to touch up a defect using the same high gloss paint just days after a new paint job!
To match your living room walls, you first need to wash them with soap and water. This process is necessary even if you decide to repaint the entire room. Paint should always be applied to a clean, dry surface.
The washing will remove accumulated dirt, grease, and smoke particles. It is virtually impossible to get an exact match on a dirty wall surface.
Get Close First
Once the walls are clean, proceed to your local paint store and ask for numerous color chip samples that are close or match your wall color. Take these back and hold them against the walls in different spots on a sunny day.
Attempt to select a color on a wall that receives indirect sunlight. Never hold a chip on a wall illuminated by a sunbeam. If you're lucky, a color on one of the chips will match closely..
Get a Pint
Proceed to the paint store and purchase the smallest quantity of flat paint that can be custom tinted to the color chip you feel is the closest match. Some paint stores or hardware stores can do this with very small amounts of paint saving you money.
I've had the best luck matching colors when I select a color that is slightly darker than the color I am trying to match. Purchase an additional pint or quart of plain white paint at the same time. You'll need this to adjust the color back at your house.
Apply a small amount of the pre-mixed paint to your wall. It may look like a perfect match when you first apply it. Many flat paint colors deepen as they dry.
The paint tends to dry darker because as the water in the paint evaporates the color pigments concentrate causing this phenomenon. If the paint dries darker, that's fine.
You'll now start to make micro-batches of paint on your own using your plastic measuring spoons and paper cups.
Take a teaspoon of the tinted paint and a teaspoon of the pure white paint and mix them together in a paper cup. Always rinse and dry the measuring spoon completely before you scoop paint from a different can.
Apply this to the wall and allow it to dry for twenty minutes. The use of a hair blow dryer will accelerate the drying time.
Adjust the proportions of white paint and colored paint if you don't get a perfect match. Keep track of the test paint areas and the proportions of paint that you mix with one another. With a little luck and lots of patience you'll probably get an exact match.
