Collection Prop Default List

I have a collection property and I am trying to figure out how to set the default list. This is what I have so far. I know that this code does not work at the monument.

class BaseColorList(bpy.types.PropertyGroup):

name: bpy.props.StringProperty(


       description="Name of tag",

       items = ('diffuse', 'diff', 'albedo', 'base', 'col', 'color'))

This is how I am assigning those values currently.

for i in range(len(BaseColor)):
    bpy.context.scene.BaseColor_list[i].name = BaseColor[i]

I am wanting this collection to have a default list when the addon is register but I cant figure out how.
