WHY DOES THE COLOR COME OUT DARK BUT DRIES DARK

I am formulating a liquid to matte lipstick. The formula is fine however I am using oxides and magnese violet for color. When I am finished the product it is very dark. When I put it on my lips it is dark but dries light...(the orginal color of the oxide) WHy is this?? Please help me thanks so much.
