On the far left is a plain, unpigmented and unpainted cast horn. Some of the interior foam can be seen at the base where the horn was cut off from the excess casting material.

In the middle is the same type of horn with a light-grey filler foam, "varnished" on the outside with black spray-paint. Spraying it on and immediately wiping it off darkens all the recesses of the casting and gives an extremely natural look. This is due to a natural horns high-points being those that get abraded and worn down, lightening the horn in those places.

At far-right is an extreme example of pigmented colour. The outer thin resin is in yellow here while the inner foam is in orange. The outer shell thins at the recesses due to the nature of the mould, and allows the inner colour to show through, albeit tinted. While hard to control, this can be exploited for interesting effects.
