Unity WebGL publishing Color Space incompatibility error

Problem:

I'm a beginner in Unity and when completing the first WebGL publishing tutorial in Essentials of real-time 3D, I get the following error:
"In order to build a player, go to 'Player Settings...' to resolve the incompatibility between the Color Space and the current settings."

How do I get past this error in order to continue the tutorial?

Solution:

One solution is as follows. First, go to Player Settings, just as the error hints.

Go to "Player". You'll see another error about color spaces and a hint about what to do about it.

Unselect Auto Graphics API.

Congratulations, you're now ready to continue your Unity beginner's tutorial and build a WebGL game.

Unpublish Unity WebGL Game

Problem:

On Unity Play (play.unity.com) I've published a game as part of a tutorial and now I want to remove it.

Warning:

Following these instructions will remove your game from Unity Play, including all saved stats, challenge submissions, etc. It doesn't look like this can be undone, so continue at your own risk.

One solution:

The following shows one way to delete your game from Unity Play. Please note that this likely cannot be undone. You'll lose all achievements, data, etc., associated with the published game, even if you republish (confirmed as of April 2023).

1. If not already logged in, login to your Unity account
2. Navigate to the page displaying all of your games. As of April 2023 this is at https://play.unity.com/discover/mygames
   
3. Open the game you'd like to edit or delete/unpublish, then look for the 3 dots "..." indicating a menu
   
4. Select "delete" or "edit", depending on if you'd like to delete or edit.
   
5. Read the confirmation carefully as there's no turning back. If you agree to deleting your game and losing any data related to it, then go for it.
   
6. Congratulations, you've deleted your game!
   

Notes:

The above instructions were verified to work in April 2023. Your mileage may vary as the Unity team is constantly busy upgrading your favorite game engine and services.
