It's difficult to choose a color from a tiny paint chip and colors darken as they dry so many people don't realize the problem until the room is finished. You think you've chosen the perfect color for a room, but when it's painted on all four walls the color seems to intensify. Using a simple white wash with a rag finish will not only tone down those bright walls, but will add texture and interest so you'll be telling your guests you planned this all along.
Mix white paint into a clear glaze in a ratio of one part paint to four parts glaze. This will give you a transparent glaze, but the color will be strong enough to tone down the wall color.
Dampen a few t-shirt rags to get ready. Wring them out until they are barely wet. Bunch into small balls to be ready for use.
Pour some glaze mixture into your paint pan. Dip your roller into the glaze and roll it back and forth until it is covered evenly with glaze.
Work in an area about 4-by-4 feet and apply the glaze randomly over about half of the area. Use a bunched up rag to move the glaze over the area until all is covered.
Move the rag around and twist your hand so that the rag leaves different impressions on the wall. When the rag is saturated, toss it into the bucket and grab another rag. Try to complete a wall before taking a break.
Remove more glaze if you feel the impressions are too heavy. Add more glaze if you cannot see enough of it.
Pounce your chip brush with glaze on it when you reach the corner, ceiling or baseboard. Use it to give these hard-to-reach areas a similar texture to the rest of the wall.
