Hello all,
PC, I'm a bit colour blind too and I had to do the lantern test which I passed. However, even without this further test I would have been able to fly as a private pilot although not at night where colours really are important.
The lantern test is much easier than the other one you did cause it only shows the 3 basic aeronautic colours which are white, red and green. If you're able to identify clearly those you should have no problem flying for fun.
Hope this helps

p.s: this was in Canada
