        m_Owner = owner;
        m_OnValueChanging = onValueChanging;
        m_InitialColor = initialColor;

        // Create custom picker UI
        m_PickerWindow = new VisualElement { name = "custom-picker" };

        // Setup picker with callbacks
        var picker = new MyCustomPickerUI(initialColor, showAlpha, hdr);

        picker.onColorChanged += (color) =>
        {
            // Send ChangingEvent while picker is still open
