Of all the tools available to you for DIY projects around your home, none are so versatile, simple and open to millions of possibilities as paint. Save for a few textile materials, just about any surface of your home can be transformed with this amazing tool.

So what are you looking to change in your home? What kind of feeling do you want a room to give off? Do you want a more dramatic space? A room with more excitement or interest? Want a hallway or bathroom to be just a bit more sassy? Apartment Therapy’s recent house tours are full of simple paint tricks to add just about any feeling to any room, with that simple tool: paint.

Drama with darker shades To start things off slowly, try using darker shades of colors you already know and trust or neutrals. Painting your walls a deep, rich gray instantly adds drama, like in Bri's Beautiful Before & After Home.

Excitement with bold It doesn't take a brain surgeon to know that bold, bright colors always infuse spaces with excitement, but we're always delighted by just how well it works. And with all the colors in the world available to you, you can choose a bold color that still feels comfortable to you. Great examples can be found in Donna & Lyla's Tiled Wonder, Ingrid & Sjaak's Colorful Dutch Abode and Jose & Ben's Light and Cheery Apartment.

Interest with pattern and graphics When just a color isn't enough excitement, adding pattern or graphics can really do the trick, as seen in Kimberly's Curated Collections and Byron & Nate's Nature-Sleek Urban Loft.

Sass with stripes Bold and dramatic in their own right, stripes get a separate entry due to their ability to really stir up a room's style. And this type of pattern is pretty easy to do! Spotted in Sally's French-Glam Hyde Park Home.

Rustic function with chalkboard paint Some folks still adore this paint trend, and others aren't so in love with it. It's still a DIY project you can do easily with paint. As seen in Jodi & Ryan's Immaculate Whimsy.
