[CIT] Spawn Eggs are invisible with CIT and custom color

[mintrefresh]

Description of Issue

When a CIT property and a custom color is applied to spawn eggs (possibly other items that use color.properties too, but this was the only thing I can test well), the item becomes completely invisible.

Steps to Reproduce

1. Create a CIT property for a Cod Spawn Egg within a subdirectory "spawn_egg" within directory "cit", changing the textures of both the egg shell and the egg spots.
2. In color.properties, set "egg.shell.cod" and "egg.spots.cod" to both have the value "ffffff".
3. Open Minecraft and check the Cod Spawn Egg in the Creative Inventory.

Can confirm, it's been a while since it's broken. Changing color.properties is enough.
