How do sample boards help in choosing the right paint color?

Sample boards sized 24 by 24 inches on primed white backgrounds isolate paint colors from surrounding influences like beige walls or colored trim. Moving these boards throughout your room lets you observe color changes near windows, shaded corners, and different light sources. This hands-on testing reveals true undertones and light interaction, aiding in precise color selection. Using sample boards provides visual clarity, boosts confidence, and cuts back costly errors.
