Update

Summarized in a method:

public IEnumerable GetAttributes(string modelName, string colour)
{
    XDocument mappings = XDocument.Load(@"D:\colour_mappings.xml");

    var q1 =
        from elm in mappings.Descendants("model")
        where (string)elm.Attribute("name") == "modelY"
        select elm;

    var q2 =
        from elm in q1.Descendants("mapping")
        where (string)elm.Attribute("colour") == "White"
        select elm.Attributes().Where(a => a.Name != "colour");


    foreach (IEnumerable attributeList in q2)
    {
        foreach (XAttribute attribute in attributeList)
        {
            yield return attribute;
        }
    }
}
