Well yes they _can_ but how? Some methods are:

1. Use a screen reader, which will speak it to you.
2. Use a browser that displays alt attributes on mouseover.
3. Look in the page source code.
4. Use some other tool that can interrogate a web page to extract alt  
attributes.

It seems to me that, for someone who just has a slight colour or  
brightness deficiency, it is unreasonable to expect them to resort to  
any of these methods. Of course, others will disagree.
