The 5 best 4K Blu-rays for showing off your TVs vibrant colors — with titles from Disney, Universal Pictures, and Warner Bros

In my opinion, 4K Blu-ray is easily the best way to view a movie at home.

It delivers unmatched picture quality that will give the best TVs a chance to shine, along with uncompressed audio that, when played through one of the best soundbars or a full surround system, is unbeatable.

Since I started testing 4K Blu-ray for TechRadar back in November 2024 as part of the Blu-ray Bounty (where we test the latest 4K releases from each month), I’ve come to appreciate the format even more, and I've even become a fan and collector during that time.

4K Blu-ray is also a staple of my AV testing, as it uses that exceptional picture and audio I mentioned to really push AV equipment to its limits.

I’ve spoken before about my favorite discs of classic movies , as I believe 4K Blu-ray has worked wonders for some older titles.

But in recent months, there’s been a few new discs that have impressed me in one area in particular: color.

I’ve tested two discs in the last few weeks alone that have entered my testing disc rotation, so I thought I’d pick my top five 4K Blu-rays for color that I’ve tried out as part of the Blu-ray Bounty.

Speed Racer (2008) (Warner Bros.) (Image credit: Warner Bros. / Future ) Based on the 1967 animated TV show of the same name, Speed Racer follows the story of a young man called Speed Racer (Emile Hersch), a racecar driver who follows his deceased older brother’s career and vies to become a champion.

After he chooses to stay with his family’s racer company, Racer Motors, instead of joining the Royalton Industries team, he becomes a target.

The movie also stars John Goodman, Susan Sarandon and Christina Ricci.

From the moment I fired up Speed Racer , I was amazed by the sheer brilliance of its colors, which practically explode on screen.

Throughout the movie, there’s plenty of bold, vibrant tones that really show off your TV’s color reproduction.

As the Racer family eat breakfast after the opening race, the bright orange walls, green furnishings and pink details all pop on screen.

Even people’s clothes have an almost oversaturated, bright look to them than when I watched on the LG G6 , one of 2026’s best OLED TVs , showing real vibrancy.
