Well, Lua stuff is still invoked via the template mechanism. If the colors are set when the page is parsed and don't change dynamically, it could improve performance if you have many color sets in an individual article (like more than 5?), but with less the performance gain would probably be negligible. Much depends on how you do it. You really should use classes over inline CSS.

As with most coding related questions, Dev wiki is a better place to ask than here. Try Lua Help board. Unfortunately, dev wiki folks aren't as quick to answer sometimes, but their answers are likely to be better.
