I grow rhubarb---"Victoria," is an heirloom rhubarb that is mostly green. It's very common in home gardens because it is also incredibly tough and adaptable. I've known Victoria patches that were 75 years old! Tastes great but---comes out greenish rather than red or pink.
"Crimson," "Canada Red," and "Valentine" are all a redder to solid red stalk. The catch? They are much pickier about where they'll grow. I live in the Southwest and can only reliably grow "Victoria" because our climate is too hot for most rhubarb. "Valentine" has an about 25% success rate here and I've never been able to get the other two varieties through the summer. If you live in the mid to upper Midwest or north of the Mason-Dixon line, you should be able to grow red rhubarb.
My mother used to cheat and add cinnamon drops to her rhubarb pies since she was going to use the spice anyway and the drops added a nice, pink color.
