Liquitex Professional Heavy Body Acrylic Paint, 138 mL Tube, Naphthol Crimson

The paint itself is fantastic but buying a jar is complicated. The first one came with a crack in it and they were nice enough to send me a quick replacement no charge.The replacement was also leaking slightly from an open seal but I cleaned it up and put the container in a zip-lock bag. Unless you're going to use the whole jar in a week or two its kind of a pain. Every time you take some out it crusts up on the sides and soon little bits get on your canvas. An 8oz tube is as large as I'm going next time. The staff here and the company itself are really good, I would recommend them to everyone.
