Floating label's initial color

Created by: LarryAzevedo

Let me start off by saying that in general, having placeholder text in a form field is not recommended. Here's just one source to explain why.

However, if we are going to be doing it in our floating labels, let's at least not make the user think that the field is already filled out; which currently is the perception:

So I propose that the initial color of the label, match that of the placeholder color: $input-placeholder-color. That will probably mean adjusting the opacity of the label onfocus:

On a side note, I'd even say that the placeholder color is too dark but I'm guessing we went with that because of accessibility?
