I'm making this tutorial because people keep asking how to change their colorset, and it's getting very annoying. So here it is, my detailed tutorial for idiots.
1. Download a colorset. This will look like
Colorset_name.zip For example i'm using Trueno's colorset.
2. Open the file you downloaded, you will see these files. Ignore all of them but colorSet.txt. Keep that opened, we'll need it later.
3. Find the server config folder. On a PC this is located at
C:\Users\USERNAME\Documents\Blockland\config\server. You will see this folder also has a colorSet.txt file. Again, ignore all the other files.
4. Now that you know where the files are, drag the colorSet.txt from the 2nd step to the folder from the 3rd step. This will pop up, just press "Move and Replace." (This is important!)
And there you have it. Launch blockland or start a server and the colorset should be installed.
Alternatively, you can type this in the console in the start game menu:
canvas.pushdialog(RTB_ColorManager);
