One of the frustrating aspects of ebook readers is the wide variance of colors when it comes to frontlights (they’re still mistakenly called backlights most of the time, but E Ink screens can’t have backlights). Even if you buy two of the exact same models, there’s a good chance their frontlights will look different.
It would make a lot more sense if each ereader had specific color temperatures that companies advertised and adhered to throughout the product lifecycle.
Right now it seems like manufactures just use whatever random LEDs they can get for the cheapest.
As a result, frontlight colors are all over the map. Some have a pinkish hue. Some have an ugly greenish hue that nobody seems to like. Some are far more yellow or orange at the warm setting than others. Some have a harsher blue tone. There’s no standard. There’s no consistency. You never know what you’re going to get from one frontlight to the next, even among the same brands and models.
When you buy lightbulbs, they show a specific color temperature on the label measured in kelvins. Warm color tones are generally in the 3000K range and lower and cool colors are 5000K and over.
How is it that we can get standardized colors for LED lightbulbs that cost $1 each, but ereader companies can’t give us a range of the frontlight color temperature on devices that cost upwards of $700?
It would be great if frontlights were more consistent, and it would be nice if the software could display the light temperature in kelvins. Once you know the color temperatures you prefer, it would be easy to dial things in how you like it.
