like in this post (switch back and forth between light & dark mode)
// a comment that in light mode might be ok but in dark mode is nearly invisible
dim foo as integer
var bar as double
for i as integer = 0 to 99
REM another comment
' yet another comment
next
all the colors in this are very low contrast
EDIT : they’re ok in light mode (although the red for comments is hard to distinguish from just about black - the red component is not saturated enough)
