Color first discovered - Fairy Tail Meme

There are three colors in the pic. Purple, black and white 👨‍🎨😃👍

I know that the image is not only in black in white but it gives the impression of it. Besides, black and white are not considered as colors so technically there’s one color.

I know, but I wanted to make a smartass comment since it's not actually monochrome...
Don't worry I still upvoted!
