i like the idea of preserved coral where im thinking itll be inbetween dead coral and regular coral so itll look like a desaturated version of it that still has color and vibrancy
terracotta stairs and slabs sound like a great idea just dont think i have enough stair variants to make terracotta stairs and slabs without changing vanilla textures
ah okay i get u just i think minecraft already kinda has those like with the concrete powders and wools and maybe glazed terracottas to some extent and theres purple/pink stairs (purpur) and blue and yellow stairs/slabs (warped or copper and sandstone or bamboo)
id say pastel is a good idea but idk how much use they would have so if pastel blocks were in the game then what builds do u think u could make with them? im thinking alien plants or fantasy castles and maybe if i implement it right it could help with gradients so ill put it on the board
