gnome shell calendar colors...

[Rob Healey]

Greetings:

Would anyone know where to look for the background and foreground colors
for the gnome-shell calendar?  I have a very hard time seeing with my
limited sight, so I need to change the colors so that I may be able to see
it...

Could anyone help me with this?
