In renders, all objects reflect the World color.
White objects are affected most, they reflect it almost perfectly. Like in reality.

Solution 1 - Emission node
Use the Emission node for the color.
That way, the object will not receive any shadows or color tint.
It will just be a silhouette emiting white light.
Might work well for 2D animation.

Add > Shader > Emission

Comparing different materials.
Even colored materials get a slight tint.

Solution 2 - Using the compositor

Cegaton's answer offers a different approach using the compositor.
Rendered objects keep grey shading, but the background color can be changed at will.

Try what works best for you :).

Solution 1 - Emission node
Set your object's color through the Emission node.
