In living color

Home movies can be a snoozefest, but “The Pacific War in Color” takes full advantage of family footage from the 1930s and 1940s that vividly brings the home front and battlefront to life. The Smithsonian Institution has mined its vast archives, which include images from Gen. Douglas MacArthur’s collection, for this eight-part series.

Pride (in the name of love)

Dan Reynolds, lead singer for Imagine Dragons, fantasizes about a world in which his Mormon religion embraces gay rights in “Believer,” a documentary from the eclectic Don Argott (“Batman & Bill,” “The Art of the Steal”). You don’t have to be a fan of his pop band to get swept up in Reynolds’ mission, which culminates in a music festival staged in the shadows of the church’s headquarters.

Amazing grace

Opera singer Kim Jae-chang may not be the most cuddly or charming hero, but his commitment to bring music to the slums of India is downright touching. Watching “Singing With Angry Bird,” a “POV” documentary that chronicles his work with a children’s choir, means enduring some off-key versions of “Amazing Grace,” but you’ll savor every flat note.

10 p.m. Monday, TPT, Ch. 2
