that's cool. use both. calculate a good default contrast server side, use proposal to allow client side to override default

  Unless it's a dynamic arbitrary colour (user-selected, overlaid on an image, etc.) then there's not much reason to be doing colour contrast calculations. Your site's design should just have well-chosen colours.

    The only reason this is a problem is because different monitors have different display characteristics compounded by arbitrary viewing environments. A client-side function can measure neither the response of the monitor nor the ambient light of the room, so this problem can never be solved in this manner.

      Both of those are already APIs today in phones. And there's decent reason to not want to tell the server either.

    So GP was relevant because that’s exactly what GitHub is doing: dynamically picking arbitrary colors and trying to put appropriately contrasting text on them.
