ColorUtility.TryParseHtmlString

Parameters

Returns

bool True if the string was successfully converted else false.

Description

Attempts to convert a html color string.

Strings that begin with '#' will be parsed as hexadecimal in the following way:
#RGB (becomes RRGGBB)
#RRGGBB
#RGBA (becomes RRGGBBAA)
#RRGGBBAA

When not specified alpha will default to FF.
Strings that do not begin with '#' will be parsed as literal colors, with the following supported:
red, cyan, blue, darkblue, lightblue, purple, yellow, lime, fuchsia, white, silver, grey, black, orange, brown, maroon, green, olive, navy, teal, aqua, magenta..

The following example creates a custom PropertyDrawer that allows the user to input html colors. This property drawer can be shown in the inspector when a color property has the attribute ColorHtmlProperty.

our custom property drawer.

// This is not an editor script.
using UnityEngine;

public class ColorHtmlPropertyAttribute : PropertyAttribute

}

// This is an editor script and should be placed in an 'Editor' directory.
using UnityEngine;
using UnityEditor;

[CustomPropertyDrawer(typeof(ColorHtmlPropertyAttribute))]
public class ColorHtmlPropertyDrawer : PropertyDrawer
{
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        Rect htmlField = new Rect(position.x, position.y, position.width - 100, position.height);
        Rect colorField = new Rect(position.x + htmlField.width, position.y, position.width - htmlField.width, position.height);

        string htmlValue = EditorGUI.TextField(htmlField, label, "#" + ColorUtility.ToHtmlStringRGBA(property.colorValue));

        Color newCol;
        if (ColorUtility.TryParseHtmlString(htmlValue, out newCol))
            property.colorValue = newCol;

        property.colorValue = EditorGUI.ColorField(colorField, property.colorValue);
    }
}

// This shows how we would use the PropertyDrawer.
