An HTML question

OK, technophiles, here’s what I want: When I use the “blockquote” tag, the font within the blockquote is smaller than the font of the regular post. Is there a way to change this without resorting to “font size=+1” every time, which seems to me to be something of a kludge? What I’d really like is for blockquotes to appear offset and in blue text, but in the same size as the regular post.
