I've just noticed that there is U+1F49C - PURPLE HEART.
I always thought that Unicode would abstract from color, hence I wonder why this symbol exists in the first place.
The next thing I wondered is how
<span style="color: red;">I 💜 Unicode</span> 💜
is supposed to look like. Should the heart be red or purple?
Chrome 61 (on Linux) makes the purple heart red. Hence it is black in normal text. But then I would expect the BLUE HEART to look identical, which it isn't (see jsfiddle).
What is the reason for this?
