颜色属性编辑器-墙外贴吧

如果你曾经希望你显式的颜色字段不再难以编辑，那就把这个脚本放到一个名叫Editor的文件夹里任何地方就可以了。

using UnityEditor;
using UnityEngine;

namespace Editor
{
    [CustomPropertyDrawer(typeof(Color))]
    internal sealed class ColorPropertyDrawer : PropertyDrawer
    {
        private const float hexWidth = 80f;
        private const float alphaWidth = 40f;
        private const float padding = 6f;

        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            // Setup:
            label = EditorGUI.BeginProperty(position, label, property);

            position = EditorGUI.PrefixLabel(position, label);

            int indent = EditorGUI.indentLevel;
            EditorGUI.indentLevel = 0;
            EditorGUI.showMixedValue = property.hasMultipleDifferentValues;

            // Colour:
            EditorGUI.BeginChangeCheck();

            float colourPickerWidth = (position.width - hexWidth - padding - alphaWidth - padding);

            Color color = EditorGUI.ColorField(new Rect(position.x, position.y, colourPickerWidth, position.height), property.colorValue);

            if (EditorGUI.EndChangeCheck() == true)
                property.colorValue = color;

            // Hex:
            EditorGUI.BeginChangeCheck();

            string hex = EditorGUI.DelayedTextField(new Rect(position.x + colourPickerWidth + padding, position.y, hexWidth, position.height), string.Format("#{0}", ColorUtility.ToHtmlStringRGBA(property.colorValue)));

            if (EditorGUI.EndChangeCheck() == true)
                property.colorValue = (ColorUtility.TryParseHtmlString((hex.StartsWith("#") == true) ? hex : hex.Insert(0, "#"), out Color result) == true ? result : property.colorValue);

            // Alpha:
            EditorGUI.BeginChangeCheck();

            float alpha = EditorGUI.Slider(new Rect(position.x + colourPickerWidth + padding + hexWidth + padding, position.y, alphaWidth, position.height), property.colorValue.a, 0f, 1f);

            if (EditorGUI.EndChangeCheck() == true)
                property.colorValue = new Color(property.colorValue.r, property.colorValue.g, property.colorValue.b, alpha);

            // Restore:
            EditorGUI.indentLevel = indent;
            EditorGUI.showMixedValue = false;

            EditorGUI.EndProperty();
        }
    }
}

改进：

直接输入或粘贴（！）六位16进制颜色代码
快速调节透明度（特别适合用于UI）
默认行为依然存在

我有这个脚本的变体已久，觉得清理一下放上来看了。
