As a patron with limited vision, it is difficult to tell the difference between the gray completed and the blue reserved. if I am looking at individual ancestors, I can see the wording BUT, if I click on a parent or spouse or child, it is very difficult to tell which color is which. Maybe a brighter blue or pink, or red would help.
Check out the Dark Reader browser extension. Perhaps by fiddling with its settings you can find some that will give you the visual discrimination you seek. I use it in its most basic mode (inverting black and white) but it has many modes and themes you can experiment with. Also, you can have it automatically turn on specified settings for FamilySearch.org (only) and leave others alone.0
I can’t find any way of leaving a new idea using iOS, either in the app or on the web browser, but this is colour related. I wanted to mention the colours used to differentiate the sexes in Family Tree..
I would prefer it if the colours for male and female in Family Tree were removed altogether. They’re a bit garish, and the various shades of colour within the images clash horribly with each other. I can see why they might be thought a good idea, but I find them a bit unpleasant to work with. The overall family tree screen is not visually pleasing at all. Is there any way you could simplify them, take out the varying shades within the male and female images, and choose calmer versions of pink and blue? Or do something else altogether?
I know it’s not a really major issue, but it would improve the overall user experience hugely.
