So might I suggest something completely horrible to work around the lack of cooldown:GetSwipeColor? I've not actually tested this at all.

do
    local mt = getmetatable(_G['ActionButton1Cooldown']).__index
 
    if not mt.GetSwipeColor then
        local swipeColors = setmetatable({}, {
            __index = function(t, cooldown)
                local color = t[cooldown]
 
                if not color then
                    color = { r = 0, g = 0, b = 0, a = 1 }
                    t[cooldown] = color
                end
 
                return color
            end
        })
 
        mt.GetSwipeColor = function(self)
            local color = swipeColors[self]
 
            return color.r, color.g, color.b, color.a
        end
 
        hooksecurefunc(mt, 'SetSwipeColor', function(self, r, g, b, a)
            local color = swipeColors[self]
 
            color.r = r
            color.g = g
            color.b = b
            color.a = a
        end)
    end
end
