Artemis is a Bukkit/Bungee/Velocity plugin that is a fork of Lunar Client's Apollo plugin, that implements a custom channel to control the Artemis mod features.

Artemis-Specific features

On top of porting Apollo's modules, Artemis adds a few features of its own that go beyond what Lunar Client itself exposes on 1.8.9 :

• Full RGB / Hex text rendering -> Artemis renders true 24-bit hex colors (the §x§r§r§g§g§b§b format) natively in the font renderer, so they show up everywhere text is drawn: chat, tab list, scoreboard sidebar, team prefixes, floating nametags, and /title / /subtitle. On 1.8.9 both vanilla and Lunar fall back to the 16 legacy colors in most of these spots. Artemis lifts that limitation.

• Hex colors in the scoreboard & tab list -> the vanilla 16-character limit on team prefixes/suffixes is removed client-side, so servers can send fully hex-colored player names and have them display correctly in the tab list and the sidebar.

• Rendering compatibility -> the hex renderer hooks the single point every draw call goes through, so it keeps working under OptiFine and alongside mods that re-render the HUD themselves (such as OldAnimations, which rolls the tab list back to its 1.7.10 version). These features are driven entirely by what the server sends: Artemis only needs the color to be encoded in the §x format inside the relevant string (team prefix, title, chat component, ...).

• RGB Colored Lightning Bolts -> the server can send fully RGB colored lightning bolts to the client. This is a feature is suggested many times to the Lunar Client discord, without any answer.
