1. Have you heard about decorative painting? This is a technique used in painting which is divided into sponging, stenciling/stamping, and ragging. By using these different techniques, it would be a lot easier to brighten the dull house paint that you now have.

2. If you prefer to sponge your wall, or rag it perhaps, paint first the base color. Leave it to dry thoroughly. Afterwards, dip the rag or sponge to the lighter color paint that you've chosen. Drag or sponge the light colored paint over your base coat; do this until you're satisfied with the effect.

3. Some people like to do stamping or stenciling when they paint their homes. This technique creates a design that looks like wallpaper over the base coat. Choose a design that has something to do with the summer. It takes just a few artistic touches and creativity to create something that depicts summer season.

4. When you talk about summer, you instantly think of lively colors. Everything seems so bright when summer comes and so there is a need to change your home's paint into bright colors. By using bright colored paints, your home will open up and it's like bringing the outside world inside.

5. Visit your local paint shops or hardware for the paints that you'll need. You can even consult the people there and ask for pieces of advice regarding painting your home with a summer theme. The people there will be most willing to test small amounts of paint for your desired color scheme.
