Color greenColor;
ColorUtility.TryParseHtmlString("#0AC742", out greenColor);

using UnityEngine;
public class ColorSetter : MonoBehaviour
{ public string hexColor = "#FF0000"; // You can change this to your desired hexadecimal color void Start() { // Convert hexadecimal string to a Color object Color color = Color.white; if (ColorUtility.TryParseHtmlString(hexColor, out color)) { // Set the color of the object Renderer renderer = GetComponent<Renderer>(); if (renderer != null) { renderer.material.color = color; } } }
}

I'm pretty new to Unity but I know that the Color constructor takes 3 parameters for r(red), g(green) and b(blue). If you understand better HEX colors than rgb ones, you should use an online converter to convert a HEX color you want to a rgb color. Then you can use : float r ; // red component float g ; // green component float b ; // blue component image.color = new Color(r,g,b) ;
