I asked this very same question many years ago to different speaker manufactures.
It depends on the cone material. A cone like a Lowther, which uses wood pulp among other things- yields a very thin, hard cone. The cone is rolled to increase stiffens. that is why there is a seam.
Bleaching the cone weakens the fibrous material.
Bozack used a mixture of paper pulp, and wool. Then dipped the apex of the cone in lacquer. I was lucky enough to see this in person.
JBL and others uses fibers that are used in kevlar. that is why they have that grey look.
Advent used a mixture of garbage bags and paper the orange Advent tweeter.
Banana fiber ( Fostex and carbon fiber has also been used.
JBL also used "Lans-a-plas" a urethane foam cone to both stiffen and dampen cone . the Le 14a is a near perfect design using this technique.
RCA and Western Electric used phenolic.
I think the Yamaya MS 10? White cone nearfield monitor was done to “look cool†and others copy it.
Today though, perhaps there is a white cone which is OK. You don't see it in pro stuff though.
Others have used aluminum ( Leak, Community), which is a sandwich cone of a skin of aluminum and Styrofoam.
There is also a UV issue in white cones.
My own feeling for white cones is the same for white bread—keep away!Of course the car speaker is in their own world.
