Hi! im making a mod with a special type of enchantments that you get from something thats not an enchanting table, and I want to give these special enchantments a red glow. Is that possible? 

Sadly this is currently not possible through conventional methods. There have been a few attempts to get this implemented in Forge, but nothing's come of it so far to my knowledge. Currently, the only clean-ish way to achieve this would be to use coremods or something similar, which can be quite complicated and requires a lot of caution. Someone more experienced than me would have to explain what that would entail.
