Hi Heather!
Sonia Kashuk Hidden Agenda Concealer Palette available at Target. If you don't have a Target near you, here's a link to purchase on eBay:

Also, here's some tips on helping correct the problems you are encountering:
-Green-toned concealer helps to counteract redness
-Salmon/Orange-toned concealer helps to counteract blue undereye circles
-Yellow/Flesh-toned concealer helps to counteract purple undereye circles
-For pimples, I found that if they are really red and raised above the surface of the skin, it's counterproductive to pack on loads of green concealer. I gentle pat green concealer over the blemish to hide the majority of the redness. Then, I create a border around the blemish with a very light beige-toned concealer (I'm very very pale, so you might need to use a darker shade..close to your skin tone) and then blend it away.
Good luck! :]
P.S. I know you said you aren't fancy but I use Ben Nye's Total CoverAll Wheel II in SK200, which is a concealer wheel that has a bunch of colors and comes in various shades. This is hardcore concealer, because Ben Nye is Theater/Stage makeup. But, it works amazing if you don't have great skin. It's a bit of an investment, especially if you don't normally splurge on makeup. But, it's SO worth it.
Here's a link to the wheel in SK200 (the lightest shades available).
