Theme Bam

Child Theme customization issue.

Links retain their default Blue and Purple color (see page area,) even though I changed them to red (see side bar)

I tried this multiple times with various colors.

Click on this link to see the current home page – the link should be dark green with a bright green highlight for testing purposes.

And here is a test link which should be green, not purple or blue. Same thing happens when I change it to red or yellow etc.

So if this is not the correct place to change the link color. WHERE can I do that. There is no other option available.
