MedianShader Color tint

How do I apply a tint here?

Object is a spriteRenderer and transparent is applied.
I would like to apply the Tint function to change the color.
Please, I want your solution.
Thank you~

Please edit your post and use code tags, it's hard to read this way : https://forum.unity.com/threads/using-code-tags-properly.143875/

But from looking at it, it seems you have a _TintColor that you do nothing with and it's not on the properties either.

Add it to the properties and then multiply what your frag returns with it.
