I'm currently re-writing my layout / UI, but on my old layout, I did this:

https://github.com/greven/oUF_Lumen/...tions.lua#L659

-- Colorize the last power color element
local function SetMaxClassPowerColor(element, max, powerType)
    if not element or not max then return end
 
    local color = element.__owner.colors.power.max[powerType]
 
    if element[max] and color then
        local r, g, b = color[1], color[2], color[3]
 
        local LastBar = element[max]
        LastBar:SetStatusBarColor(r, g, b)
 
        local bg = LastBar.bg
        if (bg) then
            local mu = bg.multiplier or 1
            bg:SetColorTexture(r * mu, g * mu, b * mu)
        end
    end
end
 
-- Post Update ClassPower
local function PostUpdateClassPower(element, cur, max, diff, powerType)
    local frame = element.__owner.mystyle
 
    if (diff) then
        local maxWidth, gap = cfg.units[frame].width, 6
 
        for i = 1, max do
            local Bar = element[i]
            Bar:SetWidth(((maxWidth / max) - (((max - 1) * gap) / max)))
 
            if (i > 1) then
                Bar:ClearAllPoints()
                Bar:SetPoint("LEFT", element[i - 1], "RIGHT", gap, 0)
            end
        end
    end
 
    SetMaxClassPowerColor(element, max, powerType)
end
