Changing color of texture with transparency efficiently

Hello!

So I am having some trouble efficiently changing the color of a texture with transparency. I have an icon that is imported as a read/writable texture and I am trying to have it change colors over time. However, the icon is transparent, and I don't want to change the color of the transparent parts.

I have tried looking up many ways to do this, but all are very inefficient and simply unacceptably resource-intensive, or they change all the colors in the texture. I am talking about the get and set pixel methods.

I am wondering if there is any way around this problem and whether Unity has an easier way of changing a single color of the texture to something else.

I am looking for some sort of setColor method that I can use, or a different way to import the texture.

Thanks.

You can create a shader to change the color at runtime. I have no idea what type change you are talking about but shader is efficient and much faster.
