I run Logos 6 + the darkest I can make the background in a very light gray. Its too light for me.
I spent the last several days on another online Christian reading system, where I have the background set at medium gray - which is just perfect for me.
Yesterday, I came back to Logos. I could feel my eyes pulse [like a heart beat] as they tried to adjust to too much light. This went on for 5 minutes.
I urge more background options be inserted into L8.
Thank you for considering this.
