I bought a very bright red from Rimmel a few years ago to complete a Halloween look and would periodically wear it when I felt I needed some color.  And was it a color because the co-workers would comment on it as soon as they walked through the door.  After looking at color swatches and checking what J likes to refer to as 'the blogosphere' for reviews, I finally decided that I wanted to try MAC Ruby Woo and MAC Russian Red.  I ended up choosing the Ruby Woo even though it's a drier formula than the Russian Red.  The co-workers have yet to comment on the Woo.  I wonder if they'll notice.
