Checking specifically for the Color::transparent value is not right. The right way to check that something is transparent is to check its alpha channel only, not to explicitly check for a particular RGB as well as alpha. We could have a minimum alpha value. It's a good insight, though, that difference from white is meaningless for a transparent or mostly transparent color.

To refine the rule, I’m not sure if simply using lightening unconditionally is the right way to handle a transparent or translucent background color. It seems we’d want to figure out the likely color from behind the text to have a good chance of getting the behavior right.

Bug fixes need to come with test cases. That includes this one.
