BrickColor

Ok so I made a function script to that if a something touches a brick, then it makes another brick turn a different color, but I wont work so here is my script

function onTouched(hit)
	Workspace.Papi1.BrickColor = BrickColor.new("Institutional white") 
wait(0)
end
script.Parent.Touched:connect(onTouched) 

So if someone could reply with the correct script that would be great! Thanks

script.Parent.Touched:connect(function(hit)
if hit.Parent:findFirstChild("Humanoid") then
part = game.Workspace["Papi1"]
part.BrickColor = BrickColor.new("Institutional white")
end
end)

I know why. Instead of Workspace put game.Workspace or workspace
