A literal flag colored red, if you or the flag is moving towards the other so fast as to blueshift it to green.

Red flag: My friend once saw what looked like people setting a RadioShack ablaze and stealing all the expensive electronics and making off with them all.

Green flag context: It was actually a faulty electronic that caused the fire, and the "thieves" were Good Samaritans saving everything from getting burned.

If a person with protanopia/deuteranopia looks at a red flag, one sees green-ish flag.

Red flags: wants constant attention, nags constantly for me to make her dinner, sometimes physically hurts me.

Green flag: when it's my cat.

Of ur moving fast enough the doppler effect.

Lying and pretending to know something who's actually a complete stranger to them

When the stranger is a drunk woman in distress clearly trying to get away from a predator.

If you’re colorblind.

Color blindness test

If your partner is indiscriminately murdering vaguely shady people with a bow and arrow it will probably be fine, cause he’ll reset the universe and become god (or something?) just be sure to weep about being betrayed at least once every seas—er… year.

Partners who want to do everything for you.

They're very giving, and will do you so many favors, and cater to your whims. Favorite ice cream? Let me go buy it for you! Need something from the store? I'll go get it! Need a ride? Got you covered!

Once they have you "locked down" (married, pregnant, in a long-term lease, dependant on them for transport, etc.) they can do a 180 and suddenly "you owe them". No more favors. Only guilt. They'll isolate you and make every negative emotion they feel be "your fault."

They want you to become dependant on them so they can use and manipulate you.

Be so very careful with overly kind/giving people. Never let yourself be 100% dependant on someone else. Ever. No matter how nice they are to you.

Piss-play fetish if you swim around the Great Barrier Reef a lot.

Multiple Personalities.

When you say you wanna see other people, they already are other people!

Sometimes a bad credit rating is a good thing

Eating in an extremely unhealthy way if you're an actor and it's necessary to gain weight for a movie, or it's for an official science experiment.
