You can use CollisionCategories and CollidesWith for this. Set different CollisionCategories for each red and brown combination and then set CollidesWith.

Something like this:

PhysicsSprite spr = GameCanvas.PhysicsObjects["box"];
spr.BodyObject.CollisionCategories = FarseerPhysics.Dynamics.Category.Cat1;
spr.BodyObject.CollidesWith = FarseerPhysics.Dynamics.Category.Cat1 | FarseerPhysics.Dynamics.Category.Cat2;
