My Paint Is Not Matching on My Wall

Color Difference in Paint

• Color is subtle. Small differences in paint are difficult to detect, and with varied lighting -- like the difference between a paint store and your home -- it is nearly impossible. Even if you do a custom mix with tints at home, paint will typically dry to a darker color than it is when wet. Inspect a mixed paint after it dries before applying it.

Finish Difference

• The difference between a semi-gloss and a flat finish can make paint look different and not match the existing finish. In this case, it is less of a color difference, and more of a difference of sheen. In certain lighting conditions, especially if seen from an angle, the paint will not match if the finishes are not identical.

Surface Problems

• Differences in absorption of sections of a wall can change color, too. For instance, if you didn't prime an area properly and the wall is more porous, the paint in that area can appear to be a slightly different color. Likewise, if there is water or smoke damage, these will show through most paints. The solution is to use an alcohol-based primer-sealer first, then repaint.

Age and Wear

• Age and wear can take a toll on a wall, as well as stains or cigarette smoke, which can color a wall. Also, pigments can age and yellow or turn duller, which means that the can of paint in the garage you used for the living room, when applied later, will look brighter and fresher and may not match your current wall color. Again, you'll want to repaint.
