How to Test Paint Colors Before Committing

How to Test Paint Colors Before Committing

Rodrigo Pereira Teixeira |

Choosing a paint color might seem easy—until you see it on your wall. Lighting, room size, and even time of day can completely change how a color appears. Before committing to gallons of paint and hours of work, it's essential to test your colors correctly. Here are the most frequently asked questions about paint testing, answered by our experts.


Why is it important to test paint colors first?

Paint chips and digital previews can be misleading. The same color can look very different depending on:

  • Natural vs. artificial light

  • Wall texture

  • Surrounding decor and furniture

  • Time of day

Testing helps you avoid costly repainting and ensures you truly love the result.


What’s the best way to test paint colors on my walls?

We recommend three reliable methods:

  • Paint swatches directly onto your wall using sample pots.

  • Use large paint sample boards that can be moved around the room.

  • Try peel-and-stick samples, available for select colors and finishes.

How many colors should I test?

Limit yourself to 3–5 colors per room. Testing too many can overwhelm you and make decision-making harder. Paint them side by side with enough spacing to compare properly.


Where should I apply the test samples?

Apply samples:

  • On multiple walls to observe how light affects color from different angles

  • Near furniture, trim, and flooring for realistic contrast

  • At eye level for easy evaluation

Pro Tip: Use two coats for better accuracy and let it dry fully between layers.


How long should I observe the paint samples?

View them over 2–3 days, checking the color in:

  • Morning and afternoon sunlight

  • Evening artificial light

  • Different weather conditions

This gives you a full picture of how the color behaves throughout the day.


Should I test different finishes too?

Yes! A color in matte can look drastically different in eggshell, satin, or gloss. Test at least your top 2 finish options, especially if durability or sheen is a factor.
