Incredible Roku, work on the web page. The characters are too light that it is difficult to read. Darken the characters, many web pages don't have that problem. I am surprised that those who work on this see it that way and do nothing. Darker letters, please. Win10 with its remedies does practically nothing.
Fonts are usually settings in your Browser settings.
You can also try browser add-ons like 'No Squint'
Maybe your monitor is too bright.
I think I do not explain myself well, I indicate that Win 10 has remedies for this but does nothing. Chrome also has its own but it stays the same, at least for me. I see other web pages with brilliance and clarity in their articles, Roku, no. This happens on other web pages too. Setting up the monitor leads to nothing, it alters the overall vision of the computer. Many websites have light colored backgrounds and the contrast with a darker background makes the reading clear. But I get the impression that Roku won't do anything about it.
The settings in the browsers over-ride the OS settings.
Anyway what you are talking about is customizing the web page
for your tastes and preferences.
You actually can do this with a user style script and an add-on like Stylus.
I think its a little advanced for you to write one from scratch and I couldnt
find a script for Roku community. You might find a Global one you like or can switch on/off.
Otherwise wear sun glasses and file a suggestion here; https://community.roku.com/t5/Suggest-a-Feature/bd-p/Wishlist
Thanks for answering, I really mean and not just customize Roku, in other pages, not all the clarity of the characters is seen, I would really only like to darken the letters a little more so that they are more visible, if many web pages do not have that problem, they do something, but Roku and a few others look much clearer than others. I tell you something too, it is only a suggestion for Roku to see that situation, if for years they are like this, and they do not see any problems, then we leave the suggestion aside. Thank you
