Colors not exactly matching

hi,
i have 2 objects that collides , and when they are colliding i want to check if they have the same color
i made sure to put the exact color, but for some reason it only works for 2/4 of the colors,
and when im checking the values it says the colors are very similar 0.02 difference,
is there a way to ignore this 0.02 , or a better way to compare colors ? ty!
btw : renderer.material.color isn't working at all

Code (CSharp):

1.  
2. public Color[] objectColor;
3.  
4. void changeColor()
5.     {
6.        currentColor = (PlayerColor)Random.Range(0, MAXCOLORS);
7.        GetComponent<SpriteRenderer>().color = new Color(objectColor[(int)currentColor].r, objectColor[(int)currentColor].g,
8.                                                                                    objectColor[(int)currentColor].b, objectColor[(int)currentColor].a);
9.     }
10.     void OnTriggerEnter2D(Collider2D other)
11.     {
12.         if (other.tag == "Rain")
13.         {
14.  
15.             if (objectColor[(int)currentColor] == other.gameObject.GetComponent<SpriteRenderer>().color)
16.                 FindObjectOfType<ScoreManagerController>().addPoints(2);
17.  
18.             Destroy(other.gameObject);
19.         }
20.     }

 

I wouldn't expect renderer.material.color to work on SpriteRenderer, for reasons too boring to go into right now.

Code (csharp):

1. public static bool ColorEquals(Color a, Color b, float tolerance = 0.04f) {
2. if (a.r > b.r + tolerance) return false;
3. if (a.g > b.g + tolerance) return false;
4. if (a.b > b.b + tolerance) return false;
5. if (a.r < b.r - tolerance) return false;
6. if (a.g < b.g - tolerance) return false;
7. if (a.b < b.b - tolerance) return false;
8.  
9. return true;
10. }

 

ty alot !

 

instead of tolerance, use

Code (CSharp):

1. Mathf.Epsilon

This is not a mere floating point imprecision problem. 0.02 is FAR bigger than epsilon.

 

if they are the same colors they shouldn't be a 0.02 difference. if they are setted the same colors, it should be enoguh to add, subs., Epsilon.

But your right, 0.02 is Far bigger than Epsilon
