It depends on the severity of the deficiency. I, like as many as 10% of men have a slight color deficiency called Deuteranomaly. It is a common form of Anomalous trichromacy, and has no effect on my work. I just have a hard time seeing some of the numbers in the circle of colored dots. (the Ishihara test) Green and brown, sometimes even green and red are difficult to distinguish. If this is your problem, you should get in okay.
If you are Dichromatic or Monochromatic your chances are slim.
