Change Brightness in emission color during runtime

How to change the brightness of emission colour in runtime.

I do this to change the emission color: "cubotemporal.transform.FindChild("anillo").GetComponent<Renderer>().material.SetColor("_EmissionColor", Color.blue);" (cubotemporal is a reference to a game object which has a child named "anillo" whose color I change in runtime).

But i dont know how to change the brightness, everytime i change the color it resets to 1.

here a picture https://gyazo.com/7ef3362f25c413fe306a44318e298b0f (I want to change the number at the right of Emission).

Hope you guys can help me, i'm stuck with this.

 

I'm no expert but when I look at the Shader, which I am assuming is Standard Shader, you can see that the Emission color has an Alpha for the Brightness.

Code (csharp):

1. _EmissionColor ("Color", Color) = (0,0,0,1)

What you are setting by using "...Color.blue);" is telling it to go to Color blue, but defaulting back to 1.

Try this as a variable for Color.blue instead.

Code (csharp):

1. BlueColor = new Color(0,0,255,8);

If I'm wrong someone correct me.

 

Maybe lerp the 2 colors?

 

Hi again. You were not that wrong... basically the 4th number has not any effect (or at least... I haven't seen it). But if you want a blue with a number of brightness "8" you just have to write this.

Code (CSharp):

1. Color blueColor = new Color (0, 0, 8);

Hope this can help somebody else. Thanks for the help

Edit: Ok, but this don't let me to combine colors, if I write for example: (3.2f, 3.2f, 8f) i get a white color, i can't make the blue more clear, i need basically something that let me modify only the brightness, so i can use the new Color to make any color I want.

Any idea?

 

That seems weird. It's RGBA. When you are doing 3.2f and getting white you are maxing out. 1f would be like 255 I believe.
