Finally, a real shower thought instead of a thinly veiled political commentary.

Not sure I've seen an orange, white, brown or purple traffic light before!

Orange bell peppers be like...

Traffic lights are the same colors as a subset of bell peppers?

Green: Go ahead and eat it.

Yellow: Caution. Delicious.

Red: Stop not eating them.

I've even seen 3-packs of peppers sold this way, with a green, yellow, and red

I've seen them sold in 3 packs as "traffic light capsicums" with a red, green and yellow one. I would have written the showerthought the other way around though as all traffic light colours (red, amber/yellow, and green) are possible capsicum colours but not all capsicum colours are represented in traffic lights (purple, orange, white etc.)

So are mangos. (mangoes?)

There's some South African grocery chains that sold a 3 pack of red, yellow, green bell peppers.

Also, for some reason SA calls traffic lights "robots." Supposedly, it's because when traffic cops were replaced by signals, it was a "robotic traffic signal."

So when you add these two things, you get...

Are bell peppers in Japan Blue?

Some supermarkets sell packages of 3 labelled as “Traffic light”

But in reverse!

I don't like green ones. They taste unripe. No go!

Yellow, meh, better but a bit bitter still. Hol-up!

Red: lessgooo!

So are bananas.
