How to change fonts and menu dropdown colours?

Hello,
On my new website template, there is no option were to customize text colour, except in the container. I would like to change the color of :
1- Menu selected page colour (now it green, I would like to change it to red #DF0101)
2- Menu dropdown colour (its also green, I would like to change it to black #282828)
3- Date, categories or author colour (I would like to put it also red #DF0101)

Thank you in advance.

Cheers,
