I'll Become the Tyrant's Tutor

Primabelle is astonished when she wakes up to find herself in a novel of her own creation as an obscure painter who gets killed by the male protagonist, Prince Rainsis. The world she created has not been kind to Rainsis. In addition to being colorblind, he has been shunned and feared his entire life, for a prophecy had been made that “the one trapped in a black and white world shall drench the empire in blood.” Primabelle resolves to disprove the prophecy after witnessing his misery firsthand. To do so, she must track down his destined other half. The only problem? All she knows about the fair beauty is that she has black hair and crimson eyes. Will Primabelle be able to help Rainsis see the world in all its splendid colors and find true happiness? (Source: Tappytoon)

If there is no “Beauty” in “The Beauty and the Beast”, then who shall lift the Beast’s curse? “One day, someone trapped in a world of black and white will appear, and stain your world with blood.” Thanks to this prophecy, the “Beast”, Prince Reynsis, was abandoned and left to fend for himself. To undo the curse, he needs the “Beauty”, but the only problem is-- "Who the hell is this beauty supposed to be?!" I reincarnated into my own, incomplete novel before I wrote about the beauty’s appearance! All I know about the “Beauty” is that she has black hair and crimson eyes...but after witnessing Prince Reynsis’ unfortunate childhood firsthand, I resolved to go and find the Beast’s beauty myself! **Note**: This is a promotional one shot manhwa for the novel.
