See https://wiki.logos.com/Night_Mode for ways to invert the colors on your PC/Mac, including Logos 6.Wilson supported this idea ·Wilson commented
Hi Logos service team. As you know the software is mostly based on reading for many hours. This can strain our eyes, hence even OS's are introducing 'dark mode'. The Logos program ranges from $70 to well over $5,000 .. Therefore the higher the price, the more likely the individual will spend time on it reading.
We the community, whether it's someone using the free version, the cheaper version or the full version really ask for a dark mode.
I can imagine this little feature may even increase your sales, it shows that the software is not only serious about the volume of books, but also takes into account the user when it comes to reading at night.
I understand that it's probably easier said than done. But I trust and pray that your team, who I'm sure can also benefit of this dark mode feature will be able to do it in due time. Thank you.
