Iā€™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) ;

For example, #ffffff is rgb(255,255,255).

Note:

Have you tried the ColorUtility class ?

ColorUtility.TryParseHtmlString( "#FF0000" , out Color myColor );'

Seems like a more suitable solution

Lets dispel few possible misunderstandings in this thread:

Unity - Scripting API: Color

Color struct constructor accepts RGBA float values in 0.0-1.0 range.

Color red = new Color( 1.0f , 0.0f , 0.0f , 1.0f  );

Unity - Scripting API: Color32

Color32 struct constructor accepts RGBA int values in 0-255 range.

Color32 red = new Color32( 255 , 0 , 0 , 255 );
Color32 also_red = new Color32( 0xFF , 0x00 , 0x00 , 0xFF );

Both Color and Color32 (32bit) can be used to define valid color values.

You can use the new Color(r,g,b,a) constructor, although it only takes RGBA float values, not Hex.

using System.Globalization;
using UnityEngine;

public class Colors
{
    public static Color FromHex(string hex)
    {
        if (hex.Length<6)
        {
            throw new System.FormatException("Needs a string with a length of at least 6");
        }

        var r = hex.Substring(0, 2);
        var g = hex.Substring(2, 2);
        var b = hex.Substring(4, 2);
        string alpha;
        if (hex.Length >= 8)
            alpha = hex.Substring(6, 2);
        else
            alpha = "FF";

        return new Color((int.Parse(r, NumberStyles.HexNumber) / 255f),
                        (int.Parse(g, NumberStyles.HexNumber) / 255f),
                        (int.Parse(b, NumberStyles.HexNumber) / 255f),
                        (int.Parse(alpha, NumberStyles.HexNumber) / 255f));
    }
}
