Summarize this article in one sentence.
Horizontal or vertical stripes can add a lot of color to a room. First, use painting tape to measure out your stripes. Next, use your roller or a large paintbrush to paint every other taped section. Once the paint is dry to the touch, remove the tape. If the original paint is dark, you may need several coats of paint on the stripes to cover it up. A large, textured painting sponge can be used to create a soft color gradient on your walls. First, dip a small part of the sponge in the paint. Next, dab the sponge against the wall. Continue dabbing with the sponge to create a soft pattern. Dab two or three colors on top of one another to create layers of bright color. For example: Layers of forest green, teal, and bright yellow paint can be used to create a garden atmosphere. Dab on light pink, dark salmon, and a dusky rose paint to add a romantic blush to the wall. Create a neutral gradient by layering beige, light grey, and soft pink paint. Wall decals can be used to add interesting designs to your walls. First, peel off the backing of the wall decal. Next, press the sticky side of the decal against the wall. Smooth out any wrinkles with your hand or a soft towel. Last, peel away the clear transfer paper. Don't peel the transfer paper too quickly or you may damage the decal. Let the paint dry for 2-3 days before applying decals. If you aren't interested in painting your whole room, add an accent wall instead. First, choose a bold, bright color that matches the decorations in your room. Next, choose a wall to paint. Section off the wall with painters tape and paint it using a roller or large paintbrush. Remove any wall hangings or light features from the wall before painting it.

Summary:
Add stripes. Paint soft patterns with a sponge. Apply wall decals. Paint an accent wall.
