 You can use [http://www.hedgewars.org/images/Team_Hat_Template.png Team_Hat_Template.png]. This is similar to the previous PNG. The hedgehogs on the right half are in gray to remind you that you only should use grayscale colors on this side.

+= Sharing hats =
+Custom hats (hats which are not part of the official Hedgewars installation) are only visible to other players if they have the hat installed under the same file name.
+
+In case the other player does not have the custom hat installed, the player will see no hat instead.
+
+You are encouraged to share your hats in the thread “[http://www.hedgewars.org/node/690 Hats! additions, submissions, information.]”, where submissions are considered for official inclusion into Hedgewars.
