(See the best response by Kaiochao.)
Code:
proc/CreateHair(STATE,MASK_STATE,ALPHA,SIZE,ANGLE,PX,PY)
    var masked_object/mo = new
    mo.icon = 'icons/hair.dmi'
    mo.icon_state = "[STATE]"
    mo.overlays += new/mask(MASK_STATE,ALPHA,SIZE,ANGLE,PX,PY)
    mo.color = "#F00"
    return mo



masked_object
    parent_type     = /obj
    appearance_flags = KEEP_TOGETHER


mask
    parent_type     = /obj
    icon            = 'icons/_masks.dmi'
    appearance_flags = RESET_COLOR
    blend_mode = BLEND_INSET_OVERLAY
    New(MASK_STATE,ALPHA=255,SIZE=1.0,ANGLE=45,PX,PY)
        transform = turn(matrix()*SIZE,ANGLE)
        icon_state  = "[MASK_STATE]"
        alpha       = ALPHA
        pixel_x     = PX
        pixel_y     = PY
        color       = "#FF0"


mob/Login()
    vis_contents.Add(
        
        CreateHair(1,1,255,0.2,45,0,5),
        
        CreateHair(1,1,255,0.35,13,0,5),
        
        CreateHair(1,1,255,1.0,0,0,0),
        
        CreateHair(1,1,255,0.1,45,0,8),
    )
    ..()
    animate(vis_contents[1],pixel_x=0,pixel_y=0)
    animate(vis_contents[2],pixel_x=32,pixel_y=0)
    animate(vis_contents[3],pixel_x=0,pixel_y=32)
    animate(vis_contents[4],pixel_x=32,pixel_y=32)


Problem description:
I'm trying to give the mask its own color but since the main icon uses KEEP_TOGETHER not even RESET_COLOR on the mask is resetting its color.

You want to use KEEP_APART to separate it from the parent.

Using KEEP_APART on the mask makes it so it isn't a mask anymore :(



Left is KEEP_APART
Right is my above code.

Since you can't use RESET_COLOR with KEEP_TOGETHER and you can't use BLEND_INSET_OVERLAY without KEEP_TOGETHER, it probably just shouldn't be an overlay. Try an alpha mask filter that masks the yellow thing by the red thing, and add both the yellow and red things to the mob's vis_contents, instead of adding the yellow thing to the red thing's overlays. Or, add the yellow thing to the mob's overlays instead of the red thing.

Possible to get a code example?

When you're using the BLEND_INSET_OVERLAY method of masking, the parent icon is the mask and it has to have KEEP_TOGETHER. The child icon (the one getting masked) uses BLEND_INSET_OVERLAY and can't use KEEP_APART or a different plane.

So I'm doing it backwards? lol
