First board RESIN/Pigment mix

Hey,

I'm building my first board,

I'm at the glassing stage. I have some questions:

- I'm using resin in styrene (Silmar 2880)

-can I use any type of polyester compatible pigments? 

-What ratio's should I use?

--> I'm going to do the top in orange and the bottom in dark orange. Using 4oz fiberglass

-I'll add some pics.

Kind regards,
