Bug Color changing its value on its own in the Inspector and odd behavior in the Inspector

Hello everyone,
I am setting color of an UI element from the script:

Code (CSharp):

1. private Image arrowImage;
2.     private Color red = new Color(255, 0, 0);
3.     private Color yellow = new Color(255, 189, 0);
4.     private Color green = new Color(0, 255, 141);
5.  
6. void Start()
7.     {
8.         arrow = transform.GetChild(0).gameObject;
9.         arrowImage = arrow.GetComponent<Image>();
10.  
11.         if(parentTransform.tag != "Player")
12.         {
13.             if(EnemyAllyList.playerEnemies.Contains(parentTransform.tag))
14.             {
15.                 arrowImage.color = red;
16.             }
17.             else if(EnemyAllyList.playerAllies.Contains(parentTransform.tag))
18.             {
19.                 arrowImage.color = green;
20.                 Debug.Log(green);
21.             }
22.             else if(EnemyAllyList.playerNeutrals.Contains(parentTransform.tag))
23.             {
24.                 arrowImage.color = yellow;
25.             }
26.         }
27.     }

So what happening is:
Colors showing different values in the inspector and in the scene then the value set in the script. Like green color value is (0, 255, 141) becoming (0, 191, 109) in the inspector on runtime. But in the debug.log it's showing that color value didn't changed at all.

Outside playmode (0, 191, 109) is looking greenish so I don't have much problem but inside the playmode the same value looking blue.

What is happening? is this a bug?

you're reading the documentation for Colours, right?
https://docs.unity3d.com/ScriptReference/Color.html

you're looking for Color32
https://docs.unity3d.com/ScriptReference/Color32.html

Colours are from 0.0 to 1.0; not 0 to 255.
