Acces shader color and lerp

Question

Hello there! I want to acces the color "EmisColor" from the mobile/particles/vertexlit Blended shader. I can easly change the color by doing this

 grid65.SetColor("_EmisColor",black);
 //"black" is a public color varible

but what I really want to do is to lerp from the current color to the black one by doing this

 grid65.SetColor("_EmisColor") = Color.Lerp(grid65.color,black,5*Time.deltaTime);

With gives me this error "The left-hand side of an assignment must be a variable, a property or an indexer" What Im doing wrong?

SetColor returns void and assigning a value to it has no meaning (hence the error).

You should use it as :

 Color lerpedColor = Color.Lerp(grid65.color,black,5*Time.deltaTime);
 grid65.SetColor("_EmisColor", lerpedColor);

That didnt work but however it pushed me in the right direction! Here is the final code

Color lerpedColor1 = Color.Lerp(grid64.GetColor("_EmisColor"),black,fadeSpeed*Time.deltaTime); grid64.SetColor("_EmisColor", lerpedColor1);
