Sounds like yours is slightly worse than mine.
Best way to describe how it effects me is this, If a plant with green folliage has ten red flowers on it the ten stand out immediatlly to a person with perfect colour vision whilst I will initially see just a few but if I stare at it for long enough I will eventually pick out all of the flowers.
I still buy the wrong colour shirts but mostly because I have bad taste.
@OP different colour yes just not red
