How about getting green dye by mixing yellow and blue dye?

Y'know what? I think that making us walk 1000 blocks just for some cactus to get green dye is actually pathetic. There should've been a feature where we could instead mix yellow and blue dye to get green dye by now, because in real life, yellow + blue = green, so please add this option where we can mix yellow an blue dye for green dye, because searching for deserts just for some cactus is already getting annoying.
