Color Mask Layers "DefaultColor" Not Loading

[Roxoriku]

Not sure if this is a bug or my misunderstanding the functionality of Fashion Sense. I don't receive any errors in SMAPI when loading my mod.

I'm trying to make a hat that is color-able but has a default color. So I utilized Color Mask Layers, defined the values and the default color.
It works well, the hat is colorable, but it always defaults to the player's hair color.

This is my hat.json file.

Thank you!
