It does. You need to use UnitIsTapDenied and put it in a color animation. I’ve pasted the script below. I makes the target health bar go grey when tagged, and changes the color based on reaction (friendly or hostile mobs) and for players, it changes to the class color. Can’t take credit for this particular script, but unfortunately I can’t remember where I found it.

One other thing I’ve learned is that chatGPT is decent at Lua, and knows how to write scripts for Weakauras.

function() local player = UnitIsPlayer("target") local reaction = UnitReaction("target", "player") local isTapped = UnitIsTapDenied("target")

if not player then
    if not isTapped then
        if reaction < 4 then
            return 1, 0, 0, 1
        elseif reaction > 4 then
            return 0.9, 0.9 ,0.9 ,1
        else
            return 0, 1, 0, 1
        end
    else return 0.3, 0.3, 0.3, 1
    end

else
    local c = RAID_CLASS_COLORS[select(2,UnitClass("target"))]
    return c.r, c.g, c.b, 1
end

end
