How would I change a brick color to the color of the brick it's touching?

For example an explosion on a certain terrain. If I shoot a projectile and it hits a green brick the explosion pieces will be green. I'm trying to get the explosion pieces to be the same color of the brick they touched. Here's what I got:

if hit.Anchored == true and hit.CanCollide == true then 
    for i=1,5 do -- # of explosion pecies
        local eff = game.ServerStorage.effect:Clone() --Creating
        eff.Size = Vector3.new(1,1,1) --Sizing the effect
        eff.BrickColor = BrickColor.new(hit.BrickColor) --*    
        game.Debris:AddItem(eff,1) --Destroying the effect
    end
end

I deleted the junk I don't need help with like bodyvelocity and stuff.
