Did you know Prince Charles paints watercolors?

Will Prince Charles ever be as beloved as his mother, his sons or Prince George, his baby grandson?

We are about to find out as the royal effort to make the next British king seem more endearing arrives on royals-admiring PBS stations next month.

The news, for clueless Yanks (the Brits already knew this): The Prince of Wales paints. And by all accounts, he's pretty good at it.

We learn this from Royal Paintbox, a documentary film by British filmmaker Margy Kinmonth, airing on PBS stations on Sept. 12.

he film introduces us to Charles' pleasant watercolors but also explores the rarely seen trove of watercolors, drawings and oil paintings by Charles' many ancestors who were accomplished amateur artists. In between are glimpses of the royal family's fabulous estates.

In the film, Charles says he's personally riveted by his ancestors' art and mindful of its endurance. "It's this feeling that you know there they were, you can sense them sitting doing the painting and everything else and then that stays behind. It's still you; it's a part of you that stays there when the rest has gone."

Charles is getting to be the family's docu-film star; this is the second major film he's hosted since his affecting 2012 Diamond Jubilee look at rarely seen family photographs and home movies of his childhood.

Royal officials have been trying to spruce up Charles' image for years, ever since his messy divorce from the late Princess Diana in the 1990s when he was one of the most despised men in Britain. That's all changed, thanks to Princes William, Harry and George, plus Charles' own hard work as heir. But he's still not as popular as they are.

Thus, the campaign to make him seem more lovable (posing with Doctor Who's Daleks, cuddling critters, cooing about baby Georgie), including showcasing his art.

Here's a modest suggestion that might do the trick: Paint George's baby portrait for the National Portrait Gallery.
