> 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.

Yes we should check for backgroundColor.alpha() while setting the textColor, as below

backgroundColor.alpha() < 0.5  (0.5 or a value which we decide upon.)

Please provide your thought.
