In brief: Probably not

If you are strongly color deficient ( such as deuteranopia) you cannot pass the Ishihara test.
If you have weaker deficiency such as deuteranomaly, you will see the richer color plates but may miss some of the subtle plates. If you have color deficiency , and want to enter an occupation requiring color normality, you should respect that standard as someone thought it meaningful.

In brief: Color blind

The ishihara color test is used to pick up congenital and acquired causes of color blindness.
The specific color plates missed form a pattern to suggest one form versus another of color vision deficiency. If you are truly colorblind, you will miss several plates on the test.

In brief: You can't pass it

The ishihara test is a test for color blindness.
If someone is truly color blind then the only way to pass the test is to cheat-get someone to tell you the correct answers. If color vision is needed for a job task then claiming to have color vision when you are really color blind could be dangerous.
