I am currently reading a book on HTML to develop websites and I came across an exercise that required me to highlight the elements in a tree diagram that would be affected by the style rule 

`div#intro{color: red;}` 

Here is an image of the solution <http://i.imgur.com/y9kYlBw.jpg>. I don't quite agree with it because I don't think you can give an img element the color red. Is the solution incorrect or is it my understanding of inheritance incorrect?
