Sometimes the color is white, while it supposed to be colored.

only protocollib and my plugin

Do you have an error log?

With paper spigot I can get an error not with spigot:

Did your client crash? Upload errors in .minecraft/logs/latest.log as well

My client is kicked

Additional information?

I tried multiple code from the api, async, not async, entity list ect... same error
I have tested with the official glowapi version and everything is fine :)

My code with the official glowapi is (almost the same I used for your plugin):

`

List<Entity> entities = new ArrayList<>();
private ChatColor color;
@Override
public void description() {
    super.description();
    Item3D i = getLastSelected();
    this.color = ChatColor.valueOf(ChatColor.stripColor(i.getDisplayName().getTitle().toUpperCase()));

    List<Projector> list = nightClub.getProjectors(color);
    list.forEach(pr -> entities.add(pr.getProjector().getBukkitEntity()));
    GlowAPI.setGlowing(entities,GlowAPI.Color.valueOf(color.name()), player);

}

@Override
public void undescription() {
    super.undescription();
    if(color != null)
        entities.forEach(e -> {
            GlowAPI.setGlowing(e,false,player);
        });

    entities.clear();
    color = null;
}

@Override
public void closeGui() {
    super.closeGui();
    if(color != null)
        entities.forEach(e -> {
            GlowAPI.setGlowing(e,false,player);
        });
    entities.clear();
    color = null;

}`
