why is this wrong

l
local component = require("component")
local shell = require("shell")

local args,options = shell.parse(...)
local color = args[1]
print(color)
--[[ this works fine --]]
for componentAddress, componentType in component.list("colorful_lamp") do component.invoke(componentAddress, "setLampColor", --[[ tho here it doesnt> --]]color]) end
