Background screen colors in IDE

The background color is transparent by default.
You can change it. The following attributes are supported:

I don't see anything in your post about changing Alpha to solid. As I said, when I set BackColor to Light Green for comments and the IDE's BackColor is Cyan, the comment's BackColor looks like muddy yellow. So I assume that the comment's BackColor's Alpha is not solid.

By default the comments background is completely transparent.

I think we are talking about different things. I'm using the following:

<Style Key="IdeBackground" ForeColor="Cyan" />
<Style Key="CommentDefaultStyle" ForeColor="Black" />
<Style Key="CommentDefaultStyle" BackColor="LightGreen" />

In the image below, B4A is on the left and VB6 on the right with the same color specs.

My question about Alpha was because I assumed that it was less than solid and the IDE's Cyan background was diluting the Comment's LightGreen. However, I just tried Yellow in B4A for comments and it looked as expected. So I guess Android/B4A just has a different opinion of what Light Green should be versus VB6's.
