Need Help With White Dye

[DemiurgeRedux]

In the past I've been able to create some new dyes by copying existing dyes and modifying the RGB codes.  However, I'm having trouble adding white dye to the game.   I tried using 255,255,255 and some slight variations thereof, but it doesn't seem to change the color of non-white items at all.

Here's my code:

<item_modifier name="modDyeNewWhite" installable_tags="clothing,armor,weapon,tool,vehicle" modifier_tags="dye" type="attachment" cosmetic_install_chance=".1">
        <property name="DescriptionKey" value="modDyeGroupDesc"/>
        <property name="Stacknumber" value="1"/> <property name="Group" value="Mods"/>
        <property name="DropMeshfile" value="#Other/Items?Misc/sack_droppedPrefab.prefab"/>
        <property name="CustomIcon" value="modDyeWhite"/> <property name="CustomIconTint" value="255,255,255"/>
        <property name="Material" value="Mpaint"/>
        <property name="Weight" value="20"/>

        <item_property_overrides name="*">
            <property name="TintColor" value="255,255,255"/>
            <property name="CustomIconTint" value="255,255,255"/>
            <property name="UMA.Overlay0Tint" value="255,255,255"/>
        </item_property_overrides>

        <item_property_overrides name="apparelTankTop">
            <property name="UMA.Overlay0Tint" value="skin"/>
            <property name="UMA.Overlay1Tint" value="255,255,255"/>
        </item_property_overrides>

        <item_property_overrides name="apparelTShirtPlain">
            <property name="UMA.Overlay0Tint" value="skin"/>
            <property name="UMA.Overlay1Tint" value="255,255,255"/>
        </item_property_overrides>

        <item_property_overrides name="apparelTShirtZU">
            <property name="UMA.Overlay0Tint" value="skin"/>
            <property name="UMA.Overlay1Tint" value="255,255,255"/>
        </item_property_overrides>

        <item_property_overrides name="apparelCoatJacketLetterZU">
            <property name="UMA.Overlay0Tint" value="255,255,255,255"/>
        </item_property_overrides>

        <item_property_overrides name="apparelDenimShortsPants">
            <property name="UMA.Overlay0Tint" value="skin"/>
            <property name="UMA.Overlay1Tint" value="255,255,255"/>
        </item_property_overrides>

<property name="PickupJournalEntry" value="augmentGunsTip"/>
    </item_modifier>

Thanks for any help you can offer.
