I love Brave, it is compact, reasonably fast and has built in ad blocking.
I am struggling with its standard colours which seem to be light gray background with a darker gray font. Is there a way to get a more traditional white on black please?
Yes. You can go and customise theme at

Many thanks, SmartyAadi 
That’s good to know but it doesn’t seem to allow adjustment of background colour or font colour?
