I am a bit inconvenienced by the use of very light grey hues. This only affects a small number posts, so not a pressing concern. Just this morning I was typing a comment to a new user, whose (totally misplaced) post was getting the usual amount of negative attention. It had reached a score of -3, and was faded out accordingly. Except that I still had to see what I was typing.
I'm in my early 50s, and I could still manage. Barely. But in less favorable lighting it might have been impossible. We have some active users in their seventies. At least one of them has confided that they occasionally have problems here due to impaired vision. Granted, such users rarely need to squint at posts at -3 or below, but anyway.
I realize that changing this one shade will cause an avalanche of other changes in the color scheme (for it to be consistent).
Just a reminder that visually pleasing to the average eye may be near illegible to a weaker one.
Other moderators (judging from the exchange in our chat room) also seem to think that the use of the greyscale spectrum went a bit too far towards the light end.
If this can be fixed by adjusting the settings of my laptop or my browser (FF v36) please tell me :-)
