Hi Brent @bkimmel > ... _I think we're converging on a point here: What I'm asking for - essentially - is the thing you called out: "add sufficient backing .....Why? Because we've had text shadow for a long time, but designers _won't use it_ because it _indiscriminately_ damages pixels_.... Not sure about indiscriminately damaging pixels... a major issue is each browser renders the shadow differently, creating content consistency issues. And some modes shut off shadow so it is not a reliable source of contrast, more of an add-on only. > _I'm going to turn on a setting in CSS that helps readability, but it won't do anything unless you choose/create an asset that traps the font in areas of low contrast and then it will only effect that area of the image"** is an easier sell, maybe?_ Realistically, nothing really helps this use-case except lowering the background contrast so that it does not compete, and kind of more my point. <img width="522" alt="Screen Shot 2021-11-10 at 6 53 44 PM" src="https://user-images.githubusercontent.com/42009457/141229474-cb853781-752d-442d-8b3c-95eb06f888a2.png"> <img width="520" alt="Screen Shot 2021-11-10 at 6 57 26 PM" src="https://user-images.githubusercontent.com/42009457/141229501-1621d9ca-d6dc-4f1f-a880-bdda9cbc4e3f.png"> > _Anyway, the core point is that you adjust the pixels _not in the text itself_, but in the _area behind the text_ so I think we're kind of agreeing here._ Perhaps, but best practices and guidelines are as I've just depicted here: reduce image contrast.... massively reduce it in this case. > _Aside: The research you put a link to there is really interesting. I'm having a fun time reading it, but the link you put in the comment above goes to `https://www.myndex.com/SPAC/` which is a 404 for me. Did you mean https://www.myndex.com/SAPC/ I'm guessing?_ DOH!! Thank you.... Yea, SAPC is the research site, and APCA is the simple version. ### _If you liked that, here are some more links for deeper diving:_ Home base for APCA research.
