Tint a mainTexture image

I am trying to tint an image, here is my code:

Code (CSharp):

1. public Texture2D image;
2.  
3. GetComponent<MeshRenderer>().material.shader = Shader.Find("Unlit/Texture");
4. GetComponent<MeshRenderer>().material.mainTexture = image;
5. GetComponent<Renderer>().material.color = new Color(1, 0, 0, 0);

If I just have this code it does tint the image but it is dark:

Code (CSharp):

1. GetComponent<MeshRenderer>().material.mainTexture = image;
2. GetComponent<Renderer>().material.color = new Color(1, 0, 0, 0);

Thanks

 

why are you setting the alpha to zero? it mean transparent

 

Was trying anything, setting it to this does the same thing:

Code (CSharp):

1. Color(1, 0, 0);

 

and if you do

Code (CSharp):

1. Color(1f, 0f, 0f, 1f);

this should be solid red, does it do something in the inspector?
any thing showing up in the console?

 

Hopefully this shows the problem better:

See attached images

with shader.png is running this:

Code (CSharp):

1. GetComponent<MeshRenderer>().material.shader = Shader.Find("Unlit/Texture");
2. GetComponent<MeshRenderer>().material.mainTexture = image;
3. GetComponent<Renderer>().material.color = new Color(1f, 0f, 0f, 1f);

without shader.png is running this:

Code (CSharp):

1. GetComponent<MeshRenderer>().material.mainTexture = image;
2. GetComponent<Renderer>().material.color = new Color(1f, 0f, 0f, 1f);

without shader and no red.png is running this:

Code (CSharp):

1. GetComponent<MeshRenderer>().material.mainTexture = image;

Notice how "without shader and no red.png" is darker than "with shader.png"
