Thank You for Your reply.
OK, here how I found it
Started at :my tribute page.( It can be any page for that matter, even starter page)
Click the rightmost icon ( one after the "Change View)
From the drop down list click “Settings” (last line on the drop down list)
New page opens where you will see Syntax Highlighting. Fonts…
Make your choice. (DARK THEME or LIGHT THEME)
Don’t forget to save the settings…
As of me being color blind:
DARK THEMES (Themes is RED!!)
LIGHT THEMES (gray bkg, LIGHT color= Teal, THEMES color = Red-ish Brown).
Under FONTS: in text: "Monaco was designed…: where (Monaco is light blue )
Save All Settings button: Light green background.
I guess I’m not color blind yet. The original black background taxes my eyes a lot. It could be due to old age, to screen resolution or something else. Anyway the white background beats any type of contrast.
