Can Opaque Pigment be used for transparent effect?

Hi there.

I am in a country where resin art supplies are limited. I am a newbie to resin casting. I want to make a transparent resin pendant but I cannot find transparent pigment available. Although, I can purchase opaque pigment for resin as that is available in the stores.

I was wondering, if i can purchase opaque pigment and use very little of it to turn the colors into transparent. does that work? Can the opaque pigment be used for transparent effect?

Thank you.
