Color guru confirms it: Yellow is the hue of the season

David Bromstad went from struggling artist with a thing for color to TV design star.

The champion of HGTV's first "Design Star" reality series in 2006, the former Disney illustrator got his own show, "Color Splash," and a line of eco-friendly paints debuted in April.

"I can't even tell you how much my life has changed -- all in the most wonderful, incredible, fantastic way," he said. "I loved my life before. I'm an artist. I paint. But I've really loved what's happened, too. I still pinch myself."

Now, he's got some tips for how to make over any room -- cheap. Think color -- as in Bromstad's favorite, acid yellow.

Not only does color lift a room, but it can lift spirits, even in small-dose accents.

Bromstad, 35, has partnered with Mythic Paint to carry his new signature hues such as Wasabi (one hot green). "I'm adding a little spice to the brand," he added. "I've always dreamed of naming my own paint colors. Now, I get to do it."

With a bicoastal schedule that would exhaust an ultramarathoner, Bromstad has been "super super busy." He lives in Miami and commutes to San Francisco to film his show.

While jetting across America, Bromstad finds time to think and plan. Of course, he daydreams in vivid color. With so many colors to choose, does he have a favorite?

"People always ask me that. It's so unfair," Bromstad said. "I love all colors."

He stays true to his mantra: "Color is the root of great design." And new paint makes a huge difference in any room, fast and relatively cheap.

"That's the smartest way to design, especially in this economy," Bromstad continued. "Paint is the most inexpensive and easiest way to transform a space immediately."

As for color trends, yellow is very hot.

"Most people don't look good in yellow, but it's wonderful on walls," Bromstad said. "Yellow is the color of the year. It's very bright, energizing. In the times we're in now, people need to be uplifted."

Bromstad particularly likes bold, bright "school bus yellow."

"It's almost a mustard: cheery, exciting, a lot of energy," he said.
