We have already Madder, Woad and Weld which turns into 3 Dyes that are the main colours, Red, Blue and Yellow. What I suggest is adding new colours which can be done through the combination of the 3 main Dyes on crafts. Such as Green etc.
And add a tool (AKA Brush) or add “Use” to the Dyes. And make ourselves able to paint the tiles and walls.
That is an update that would add tons of customization to everyone on their houses and will add new players who enjoy playing with buildings and colours to make cool stuff.
Cheers
