About the toys
00-20 Platinum cure Silicone. Colors are achieved with Silicone pigments, and detail painting uses thickeners to allow the material to be painted on before it cures. All material is vacuum degassed before being applied to the mold.
00-10 hardness silicone is also available. that this material has more give for individuals with a greater diameter than average, as well as a different feel when used. However this material has additional quirks which makes using it in a production environment difficult, and will incur an additional fee if applied for.
Both 00-10 and the thinned variety are more susceptible to having permanent indents applied if the toy is gripped with sharp points ( So, fingernails, or pushing with one finger REALLY deep into the mass. )

My ponut has a hole on top!
That's a tailhole, by design. 
Early on in the lifetime of the toy, it was planned to have customizable tail attachments. During testing however, this was found to be impractical to leave in during use, and to custom make tails for any possible combination.
Through feedback, it was decided to be left in so that anyone who wants to, could apply a tail.
This Tailhole will no longer be present starting January 29, 2023 onward.
Can I just paint ON the toy? Like with makeup? Or more of the silicone?
And using more silicone is going to be even worse.
I'm going to go out on a limb and assume most folks haven't used "Paint" beyond watercolor sets when they were kids, spray cans, or jamming a wide brush into a can of unthinned paint and then slapping it against a wall surface to color it. The best case scenario for this is someone who regularly paints model figures, but that's still not a great start, gonna be real.
Even if you're okay with the added material delaminating, you're going to have very obvious brush strokes and raised surfaces, on top of the bubbled surfaces you'd be introducing without a vacuum chamber. Assuming of course the painted material didn't run. Or congeal into stiff peaks.
You'd be doing a repeat of the Ecce Homo, except with rubber and genitals.
