How much color gamut do displays really need?

In my last post, which focused on the trend towards ever higher resolutions in smartphone displays, I suggested that color performance might be a more useful area of focus for display makers. That’s because, in terms of color gamut, we are a long way from reproducing the full range of colors that our eyes can detect.

For context, let’s add the color gamut of one of the most popular smartphones on the market, Apple’s iPhone, to the chart from my last post:

Best performing smartphones in resolution vs iPhone color gamut performance since 2009.

The latest iPhone only covers about 1/3 of the range of colors our eyes can detect so we’re a long way from matching the acuity of the best displays on the market in terms of resolution. But, how much color do we really need for a great experience?

As a display technologist and color blogger that’s probably the question I’m most frequently asked. If I’m advocating for more colorful displays, how much more am I after? There’s got to be a reasonable limit right?

Perhaps unsurprisingly, the short answer is that it depends on a lot of things. Different applications, from ecommerce to the TV on your living room wall, all require differing amounts of color performance. The environment matters a lot too, if the display will be used outdoors brightness may be a factor. There are slowly evolving broadcast standards and content delivery infrastructure to consider as well. And, of course, technology limitations– what can be achieved today and at what cost?

These are all valid concerns for anyone designing and marketing a new display product but they don’t really answer the bigger question. To me, what we really ought to be asking here is: what would the ultimate consumer experience be in terms of color? To answer that, I think we first need to take a step back, put some the practical stuff aside for the moment, and define what that experience should look and feel like. Once we understand that we can start to put the technological pieces together to achieve it.

What do we want?

So, let’s first ask: what do we want? In a pie in the sky, ideal display, in terms of color performance?

Well, the engineers among us are probably thinking, first and foremost, it has to be accurate and that’s a great place to start. Our displays need to accurately reproduce colors found in nature for increasingly important ecommerce applications, photos we take of our family should look real, not over saturated and professionally created content should be reproduced so that it conveys the artist’s intent without distortion.

But, maybe the marketing folks among us have another criteria in mind and that is a bit more subjective. We want our displays to be immersive and engaging. We want them to jump off the shelf at retail and we want to deliver a unique and exciting experience to our customers.

Can we have both?

To find out, I’ll be taking a look at how we perceive color in my next post.

  3. Tks for your post. But I really know how could you measure a smartphone gamut color? Or how can I decide how much color gamut of my smartphone.

  4. The ideal monitor would display every color that the human eye can see. In other words, every color in the CIE 1976 chart. Display R&D should not stop until we are able to view the ACES color space in its entirety.

    Since we presently don’t have the technology to do this, we should focus on increasing the color gamut to the maximum amount possible with the technology that is available.
