This needs to be topColor.hasAlpha()

Not a huge fan of the name (would prefer something like colorDistinctOverColor() or something),

Can this just call blend() and check if the result == bottomColor?

> +    if (bottomColor.red() == topColor.red() && bottomColor.green() == topColor.green() && bottomColor.blue() == topColor.blue())

Would be nice to push this into Color. (colorComponentsEqual or something).

> +    if (!topColor.alpha())

hasAlpha? Do you care about how much alpha?

Seems iOS builds are complaining:

Source/WebCore/editing/FrameSelection.cpp:1477:20: error: unused function 'disappearsIntoBackground' [-Werror,-Wunused-function]
static inline bool disappearsIntoBackground(Color foreground, Color background)
1 error generated.

Needs to be wrapped in #if ENABLE(TEXT_CARET).

Also, is == too strict? Should we have some threshold for close colors?

Build issue was fixed in http://trac.webkit.org/changeset/175155

I mentioned the perceptive matching issue to Myles; he didn't want to get into that rat hole.
