Robert "Bob" Ross is best known for creating what was (and still is) the most relaxing show to air on American television. To watch him was to love him. In "The Joy of Painting," his PBS series that ran from 1983-1994, Ross introduced the world to "happy little trees," and "majestic mountains" in a way that showcased his love of painting and nature. He was the Mr. Rogers of painting — calm, sincere, gentle and encouraging.

"The Joy of Painting," is no longer on the air, and sadly Ross is no longer with us. But thanks to YouTube, his legacy lives on. A few weeks ago, an absolute gem of episode resurfaced. In this episode entitled "Shades of Grey," Ross explains that he had recently been approached by a man who had said that he couldn't paint because he was colorblind and could only see gray tones.

"So I thought today we'd do a picture in gray just to show you that anyone can paint," says Ross.

Ross traded in his usual palette of "gorgeous greens," and "stunning purples," for various shades of gray. Using only Prussian Blue and Van Dyke Brown to create his grayscale, and Titanium White to highlight and "add some sparkle," Ross proceeds to spend the next 26 minutes creating a masterpiece in black-and-white.

Ross narrates while painting, “Isn’t that fantastic? That you can make whole mountains in minutes? And you can do it. There’s no big secret to it. All you need is a dream in your heart.”
