I have a color-blind friend who lived to be a PO here in Michigan. He went to his eye doc to get the basic checkup and couldn't do the tinted plate test (can't remember the exact name of the test). The doctor told him that he was so bad that he didn't even charge him for the visit.
It all depends. He did some research into this because this was a lifelong dream---both of his parents are/used to be PO's. I did some research too into MCOLES records and found a few cases that were brought to the commision and were granted. You might have sue---thats what a few people have did and won. I believe one case was in Dearborn. My friend ended up giving up on it...I think he still depressed about it two years later.
Check the MCOLES commision meeting minutes or search if you can.

Some insight from one who has been plagued by color vision problems himself:
The most commonly used test, and the one to which you refer, uses what is called a pseudoisochromatic plate: Figures, letters or numbers hidden within a field of dots. It's also known as the Ishihara or H-R-R test. It is primarily a screening test, and is not the most precise one available. It is widely used because it is (a) simple to administer and (b) cheap. Its main weakness is that it is dependent on the kind of lighting used when it is given...daylight or a specific type of incandescent is best. Not everyone knows this (including some doctors). The plates can also become faded over time, which reduces their accuracy.
If you can't pass this test, there is an alternative. It is called either the Farnsworth D-15 or Farnsworth/Munsell 100 Hue test. You have to hunt around for these, since the equipment is not readily available and is also rather expensive. I managed to find the FM 100 at a local county medical center here in NY. They told me that they frequently give this test to LE candidates because most NY agencies (Corrections, University Police, etc.) accept these results from those who can't pass the Ishihara. FWIW, I passed the FM 100 with, er..."flying colors" (forgive the pun) whereas I stumble through the other kinds of tests. It also set me back just over $200, but it's worth it.
As mentioned earlier, check with the agency to which you're applying and find out what specific color vision tests they'll accept.
Best of luck. Hope this helps.
