You have some lovely neutral pieces to begin with! The easiest way to introduce color is with a colorful rug in your living area. That will inspire the color of pillows, art, etc. It will also help you create spaces in your open concept L. You might pick a color from your rug and lean into it with the cushions in your bar stools, for example. Or art in the dining area. Even accessories in your kitchen. What are your favorite colors? What colors are you drawn to? What color clothing do you like to wear? Look in your closet for a start. And have fun with this. Your foundation is good. Now start building your space to reflect you!

We might suggest trying some large plants, some artwork with yellow in it for the one room, and more pillows for the TV room. You could also look at adding lamps to the TV room, along with replacing the fan with a chandelier. See some of our designs images, included here.

The second photo, the TV area, looks like the one that needs some work. If you want to add color, try adding some textured pillows to the furniture, a tall plant and floor lamp to the area. We might also suggest trading out the fan for a nice chandelier. Below are some visuals to help you more:

This is the second time I've posted this inspiration photo today, and I don't normally like accent walls. However, your huge TV screen is dominating that end of your space,. Do consider an accent wall in a beautiful, non-neutral color with surrounding art or light wood shelves with items you like.
