How To Capture the color from screen in mouse position using Unity and C#?

Question

I did not find a direct function in Color section or since there is no direct C# Unity function for picking the color from post render. How is the best approach for picking the color in the mouse position?
I have done research and looks like there is posible to make a screenshot and then look into the texture calculating the mouse position.

Input.GetMouseButtonDown(0)

Application.CaptureScreenshot("Screenshot.png");

// get the color pixel in the same coordinates of the mouse position
Vector3 mouseCoordinates = Input.mousePosition;
myFinalColor = tex.GetPixel((int)mouseCoordinates.x, (int)mouseCoordinates.y);

Or do I have to make a second camera and attach it to a mesh render?

You just need to use GetPixel(x,y)

This is very simple.

• Save Screenshot to Texture2D for example MyTexture
• And add .GetPixel( x postion of moue , Y position of mouse )

• Save it to your color for GetScreenShot ( make your View to Texture2D )
  
  

      Color TheColorPicked;
      if (Input.GetMouseButtonDown(0))
      {
          TheColorPicked = MyTexture.GetPixel(Input.mousePosition.x,
                                                 Input.mousePosition.y);    
      }
