With a Delta E of 3.4, the difference is enough that they should not be used on adjacent walls in the same room. You can use them in separate rooms of the same house, but be aware that walking from one room to the other may reveal the difference, especially if the rooms have similar lighting. For the most consistent look, pick one brand for all connected living spaces and reserve the other brand for visually separate rooms like bathrooms or bedrooms behind closed doors.
There are several practical reasons to look for a Behr equivalent. Price differences between brands can be significant on large projects. Availability matters if your nearest paint store or home center specializes in Behr. Some painters have strong preferences for one brand's formula based on coverage, dry time, or workability. And if you are touching up existing Behr work, matching within the same brand gives you the best consistency for seamless results.
