What is the default window border theme?

For the cinnamon edition, what is the default window border theme called. I would like to use it on other distros.

Matcha

Isn't the default mint-themes now?

Matcha seems to be close. I cannot find the Matcha theme anywhere but I did find this theme but the close button (X) is small. I remember the default window borders theme in Manjaro to have a big red X button as the close button and the min and max buttons to be small.
