I can use the Libra to read during the day and the Oasis for in the dark?

Kobo just has so many features I like it's hard for me to write them off all together because I don't like the lighting.

Yeah, can't wait to hear what your experience will be! Hope it'll be better than the previous ones!

Have you all seen these reviews? They're the only reviews where you can see how uneven and green the lighting on the Libra is (or that particular Libra, perhaps not all).

Camera white balance seems odd. Doesn't make much sense to have a green tinge

That was my first thought, but, when they show the screen without the light, or with the Oasis next to it, it doesn't appear to be white balance. I don't think I have seen another like that. Mine is definitely not greenish at all.

Just thought I'd mention that if you turn on developer's mode you can adjust the LED colours manually.

To do this enter devmodeon into the search bar and then go to Settings>Device information>Developer option>Light Settings.

Developer options is at the bottom of the Device information page. Once on the Developer options page tap Setting under Light Settings and you will be presented with slider adjustments for red, green, blue, and white.

Just adding that when I played around with the green setting I was able to get my screen to look like those on the videos posted above.

Wow, really?? That would be so awesome!
I'm going to try it when I receive mine.

Sirtel showed some pictures of the Libra and Oasis 3 next to each other in different lighting settings and the Libra screen was definitely green. (I don't know which thread that was or if it was in this one)

I've found on my Aura One they behave very oddly though.
If you set green and blue to 0, you can get a nice range of orange and red by changing the red slider.
As soon as you set green to even 1 (out of 255), the entire colour switches to a white/green hue.
Hard to explain without being able to show it.

Yep, that's with the comfort light off. I'm not really bothered by it, but I'm going to play with the dev options now too. Thanks for that tip.

I have green set at 106, blue at 0, red at 153, and white at 136. At this setting mine appears neutral to me. Once I set blue at about 80 with all other settings unchanged, the screen. appears purple.

Seems like there might be a lot of variation in this as with the screens and lighting in general.

I just tried this out of curiosity but the Light Settings are not there. Maybe it's not available for the Libra?

Just received my Libra, the settings aren't there either.

And since this Libra screen is pretty green I would love to be able to adjust the LEDs

Libra Green???
On the slider it varies from bluish white to amber white. At about 3/4 towards night it matches the colour of my bedside light, though the lighting isn't needed at all, anywhere in my house.
My Libra H2O never looks even slightly green at any setting.

NiLuJe · 11-06-2019, 10:44 AM

Individual LED control is only available on the Aura One

.

The option used to be mistakenly available on other devices w/ color LEDs (in the debug menu), but I think that's no longer the case on current FW version.

Mine looks green in a dark room. Not in daylight or in artificial light.
