See https://wiki.logos.com/Night_Mode for ways to invert the colors on your PC/Mac, including Logos 6.Jay Baldwin supported this idea ·Jay Baldwin commented
Love Logos. HATE the dependence on white-only. Can't say how much it would benefit me (especially as Apple has even changed to Dark Mode in Mojave) to not be so incredibly jarred when I switch to Logos. I'm starting to feel like I have to wear sunglasses to use this product! PLEASE, developers. I'm a Software Developer - I know it isn't that hard.Jay Baldwin commented
This is really a no-brainer. It's actually painful to use Logos on my phone in bed at night. Most apps, especially reader-based apps (even free ones and bible ones!) on my phone have Dark Mode. The very premium Logos library and its reading app does not.
