I hate to be a bother but I've been really digging deep into this plugin (making a personal guide as well)

I haven't been able to find a guide anywhere as far as the acceptable text colors and commands it will accept.
On text colors:
I checked the en.yml and saw that colors like silver and etc were used however when using them inquest text prompt "wordshere words here"
Some refuse to work, others do but from testing; Brown, Gray, lime, magenta, silver, orange, cyan and lightblue so far will not work.

I've juggled between minecraft text color codes and .

As well it seems text color codes absolutely do not work with objective display override.
I am fine with it being green just unsure if text codes are supposed to work there.

 On commands:

I am just completely lost on how to get command events to work.
Are they limited to only vanilla commands?
Some way to extend into other plugins commands?

   On initial events:

Every time I've set up a quest and inserted an 'initial event' it somehow gets removed and I am left with attaching the event to stage 1 instead.

Thanks for the time and work.

If it's text then here are the acceptable colors: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/ChatColor.html

Perhaps you were looking at this, which is used for particles and dyes: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Color.html

As for the other questions you'll need to detail the steps you took.

Ah ok so the second link is indeed what I was looking at for chat colors and thought maybe quests plugin extended acceptable chat colors. Though I know better now apologies and thank you.

The steps I use for commands on events and quests are as follows.
/quests events
2-edit events
-eventname-
17-set commands to execute

Then during the commands prompt I've attempted using slash(/) and without slash and cannot get it to run some special commands.
.
I had wanted to possibly have quests run a ranking command to rank a player with bpermissions or similar. As well I wanted to have it possibly run the spawn command for mythic mobs.
Another command would be when the player triggers the event it would do a server announcement via broadcast command. "player has done xxx" or another.
A command to perhaps /press button /toggle lever
Of course these would rely on quests being able to prompt into other plugins commands.

Internally allowing an event to force a player into a quest, like a event that would use questsadmin @p or and force them into another quest or progress the current quests stage.
The applications are immense if I could given the event triggers.

Those are just a few command options among others I can possible think of applying. I haven't been able to get anything like above to actually work.

As far as the other question I follow this process to insert a simple initial event that prompts text and gives the player a boat.
/quests editor
2-edit a quest
-questname-
8-set initial event
-eventname-
13-save
1-yes
/questsadmin reload

At this time quests are reloaded. Upon using /quests editor and going into the quest I just saved with an initial event the initial event is now (none) despite actions formerly took registered the initial event with (eventnamehere)

Speaking of events and the way they work I might ask why on a stage is each event trigger limited to one event, it would be very interesting to affix a specific event to specific chat words instead of one event for any of the chat words. Allowing for a multitude of effects, in example a user says fuck they get slowness triggered, a user says shit they get blindness. Combine the multiple chat event triggers with commands and the outcomes get interesting and endless.

I apologize to unload such a huge wall of text.

Sorry to put another small wall of text but I had forgotten to add the portion of text colors for the override objective portion.
/quests editor
1-create new quest
-named-
11- edit stages
1-add new stage
20- custom objective ----------Here is where I've attempted to use color codes only to have it display as:

As you can see option 22- set start text- Will display proper color codes as does 23-set finish test
I wasn't sure if custom objective display was locked at only green or if this was an issue.

However I have found an issue it is in regards to using color codes for a quests name.
Unfortunately the quest you see above I can no longer edit!
As after the quest is saved it applies the color codes and removes them, but they are still a part of the name.
The gui seems to think Color Code Test is an invalid name I even tried Color_Code_Test and with &4Color &3Code &2Test with no success.
The fate is the same for & color coding and <> Color coding.
Which leaves me to forcibly go into the quests.yml to edit the quest or remove the color coding.

Sorry about the close/re-open, accident.

For your first question regarding commands, I cannot duplicate that on my test server. I used Essentials' /bcast success! as my test command. In the event editor (/quests events), I created a new event and Set commands to execute as "bcast success!" without the / (using the / just runs the command). Then, in the stage editor (inside /quests editor), I set the start event for my quest as the event I just made. Upon taking the quest, I saw "[Broadcast] success!" in-chat.

For your second question about colors, quest names are not intended to support that. This is evident in your picture by the ")---" following your quest name keeping the green color instead of staying gold. If you would like to request this feature, please open a new Issue with that information and I'll get to it once the remaining bugs have been ironed out. For now, avoid using colors in quest names.

On that note, I actually will close this as your original question has been answered. Gracias! :)
