RE: Inline Style Sheet Question

Just to make sure that I understand what you are saying...
If there is a style in the author's style sheet that just makes the font
red, for example: 
	.red {
		Color: red;
	}

Then I must have that same class defined in my user-defined style sheet?
If this is the case, is there a way to get around it?  How is a visually
impaired user supposed to know what additional styles to use for each
web site they go to?
