Why do some colors have 8 hex digits?

[jsonnentag]

In testing out the latest (Beta 2) I was going through changing colors again (since the fonts settings don't modify the Play/Episodes/... text) and noticed in multiple places that some color values have 8 hex digits rather than just the 6 (2 each for red, green blue). I am GUESSING that at some point you did a search and replace and some digits were left or something. (???)

Anyway, it appears that they are ignored when processed. As far as I can tell they are anyway.

Here are the locations I have found:

fontsupport.brs (down at the end for the default font)

EpisodesListItemComponent.xml (title, info, and description settings and I think rectangle color has extras too)

[jsonnentag]

This is somewhat different, but a question about the fonts. . . .

Do you know if the font size setting has ZERO effect if the font is set to a system one (such at those listed here).

I got rid of all the fonts except for the dot used in the videos extras info line and just put the system ones to save file space and since I'm OK with the system ones (well, and I don't like the italics one because it is too hard to read).

What is the massive sized (859K) NotoEmoji-Regular.ttf font used for?
