Have no idea why but the highlighting color isn't applying for §a, §3 and §6 ;(

Just checked - works for me.

You could try use another values for color in settings i guess. Or try to remove some lines of settings and see whats happen.

Not working. I tried deleting other lines and changing the color but the colors are still not applying, however it's pretty weird that I just tried replacing §3 with a random letter say §p, the color successfully applied. Sorry for bothering, I might have to troubleshoot that myself.

Sorry for all that. I was all new to Highlight extension and I left highlight.maxMatches at its default value, plus the lang I've been working on was massive, leading to what I thought was a bug or something. Anyways thanks for the neat setting!
