No, black. Red has an extra high activation point and much lighter springs (marketed to gamers for quicker reactions) that often misfires when the user rests his hand on the board and doesn't take special care not to press anything. Black is the standard office class linear one of the bunch with the weight matching brown and blue.

Personally I'm fine with the occasional misfire to keep the nice light, floating typing experience that reds give. Blacks just feel a bit too heavy to me. It's all personal preference of course.
