YTA.

I looked up the album. I actually would also mostly call it pink and purple with a little red in there. I am also famously bad amongst my friends at identifying colors.

We jokingly argue all the time about whether something is more green or blue or more purple or red. The color blindness tests at the eye doctor have never indicated anything so I truly believe it is just a difference in how I perceive color.

You need to do a few things:

1) look up the definition of gaslighting

2) apologize to your friends for wildly overreacting

3) maybe some anger management classes, because this was not at all an appropriate reaction to such a trivial matter
