I love these types of reds, ones that are just sheer enough that when layered they create a beautiful deep red. I had recently seen this on Strych's blog 'Pretty in Dayton' and had to copy immediately. I usually wear my red's like this anyways, but thought it would be fun to do a comparison/ tutorial.
As you can see in the photos above and below, the black base makes a huge difference with this polish, while the white brightens it up just a tad. Hope my pic's are self explanatory, but;
