TWebMemo doesn't respect font colors

TWebMemo font color is not respected. Works in the IDE, but doesn't work in the browser. ie, I want to set WebMemo1.font.color := clLime;
How can I change the font color?
If this is a CSS thing, please tell me explicitly how that's done, because I'm unfamiliar with using CSS at this time.

I created a new TMS WEB Core project and dropped a TWebMemo on it and added the code:

procedure TForm1.WebButton1Click(Sender: TObject);
begin
  webmemo1.Font.Color := clBlue;
end;

and this worked to change the font color to blue. What are you doing differently?

I don't think I'm doing anything differently. I changed from clLime to clBlue (just in case), but the font color in the browser still doesn't change.
I also rebooted the computer and cleared the Chrome cache.
If this is not reproducible by you, I'll keep experimenting and see what I discover. I'm new to Web Core (2.8.1) and don't have earlier versions I can test with.
My goal is to use a WebMemo with a black background and clLime font color, to emulate an old CRT monitor. Works great in the VCL.

This is my test:
