How I can change Sprite Renderer color with C#? I need use RGB color.

GetComponent<SpriteRenderer>().color = ... and what I can write after?

 

Change the RGB 0-255 to RGB 0-1.0. This will allow you to get the correct float values to assign like so:

spriteRenderer.color = new Color(1f, 1f, 1f, 1f); // this is white with zero transparency

You could also use 0-255 scale if you use Color32, which is the 32-bit version of a color.

spriteRenderer.color = (Color)(new Color32(228, 80, 80, 255));

This explicitly converts Color32 to Color. You can probably eliminate the (Color) because there's an implicit operator that can convert it automatically. I've included it just to be clear about what's happening behind the scenes.

 

This should/may give you an idea.

Code (CSharp):

1. public class ColorChanger : MonoBehaviour {
2.     public SpriteRenderer spriteRendererToChangeColor;
3.     public Color colorYouWant;
4.  
5.     private void Awake(){
6.         spriteRendererToChangeColor = GetComponent<SpriteRenderer>();
7.     }
8.  
9.     private void Start(){
10.         ChangeColor(colorYouWant);
11.     }
12.  
13.     public void ChangeColor(Color color){
14.         spriteRendererToChangeColor.material.color = color;
15.     }
16. }
