New VIBRANT yellow blocks (such as the gold block)

Maybe in the next update add a bigger variety of vibrant yellow blocks, I think these could bring a lot of creativity to Minecraft and fit perfectly into your new adventure theme, you could add a new block to the sulfur caves, it could be a more vibrant with a smoother texture sulfer block that has special properties such as making a faster elevator or being able to use the brush on it to get a item like suspicious gravel & sand. Please consider this.
