Sniffers should dig up new dyes

Sniffers being able to dig up ancient seeds is a really neat idea, but I think it would be even cooler if they were able to dig up new flowers with new dyes, such as different shades of existing colors (Dark red, neon yellow, light brown, etc.). Having the sniffer dig these specific dyes up will be much more interesting than the current way to obtain dyes. Some of the colors can even be from the old set of wool blocks in Minecraft Classic. I think the whole sniffer being ancient thing can tie into this extremely well, considering how those past wool blocks are now ancient themselves, being over a decade old. These new dyes will of course mean new concrete and terracotta blocks as well, which can expand players' creativity even more. 

Also, I think as a cool easter egg sniffers should be able to rarely dig up the old rose and blue rose flowers, which are nostalgic for a lot of veteran Minecraft players.
