Worldbuilding - Explore Every Impossibility

No, seriously, I'm so TIRED of dark and gruesome fantasy worlds, not only fantasy, sure, but with fantasy it's specifically turning out to be a common thing between authors to try make everything depressing and violent

It's getting to the point that I don't feel any interest in new western fantasy books (because african and asian fantasy is way different and more colorful in general, but it have a cultural reason behind as well)

I had been reading some classic authors like Terry Pratchett and Ursula Le Guin and it's so weird to me as new authors seem to feel a type of allergy when it's about using colors or describe basic human decency in their worldbuilding, and it's not saying that more serious plots is not welcome, but you can have a mature audience enjoying a very colorful world, you can actually explore a deep disturbing dark story in a very colorful world (could say it would be way more upseting reading such plot in a happy fairy tale like world than in your stereotypical "medieval" dark age setting)

ASOIAF is great, I know, but seriously not EVERYTHING need be the next ASOIAF or The Witcher
