How to Match New Paint When You Don’t Know the Original Color

Trying to touch up or repaint part of your home only to realize you have no idea what the original paint color was is more common than you think. Whether you just bought the home, tossed the old paint can years ago, or the color faded over time, matching paint can feel tricky… but it’s absolutely doable with the right approach.

Here’s how professionals handle it and how you can avoid the most common mistakes.

1. Start With a Paint Chip Sample (The Old-School Method)

One of the most reliable ways to match paint is by removing a small physical sample from the wall.

Best places to take a sample:

• Behind outlet covers

• Inside closets

• Behind appliances or wall hangings

Cut a piece about the size of a quarter and take it to a paint store. Most stores can scan the sample and create a close match.

Pro tip: Make sure the sample is clean and flat no dust, grease, or texture chunks.

2. Use a Paint Color Matching Tool or Scanner

Many paint stores and contractors use digital color-matching scanners. These devices read the color and formula a custom mix.

What to know:

• Results are usually very close but not always perfect

• Lighting, wall texture, and sheen can affect accuracy

• Older or sun-faded paint may not scan consistently

This method works best when you’re repainting a whole wall, not just touching up a small spot.

3. Match More Than Just Color Sheen Matters

Even if the color is right, a mismatch in sheen will stand out immediately.

Common interior sheens:

• Flat / Matte

• Eggshell

• Satin

• Semi-gloss

Touch-up paint in a different sheen will “flash” under light and look patchy. When in doubt, compare the wall’s reflectivity at different angles.

4. Expect Touch-Ups to Still Show (Even With a Perfect Match)

Here’s the honest truth most homeowners don’t hear:

👉 Touch-ups almost always show.

Why?

• Paint ages and fades

• Walls collect oils and dirt

• Original paint may have been applied differently

That’s why pros usually recommend repainting corner to corner instead of spot touching.

5. Test Before You Commit

Never paint straight from the can.

Do this instead:

• Apply small test patches

• Let them fully dry

• View them in morning, afternoon, and evening light

Paint changes dramatically depending on lighting.

6. When Matching Isn’t Worth the Headache

If the wall is:

• Highly visible

• Large

• Or already worn

…it’s often faster, cleaner, and better-looking to repaint the entire surface.

A full repaint ensures:

• Even color

• Uniform sheen

• No patchy touch-ups

Final Pro Advice

Matching paint without the original color is part science, part art and part experience. Small differences that homeowners miss are immediately noticeable once the paint dries.

If you want it done right the first time, a professional eye makes all the difference.
