Color Wheel
For those that find the paint tool too restricted, this mod allows the player to change the hue of any block.
The Color Wheel can be crafted from the Inventor’s Table using 20 timber, one blue dye, one red dye, and one yellow dye.
How to use: open the Color Wheel, put a block (or block stack) inside, and choose the color; the hue of the block is immediately changed.
Do note, however, that while the Color Wheel can change the hue of any block, changing the hue of blocks that lack any color from the start has no visible effect; pure gray is still pure gray regardless of how its hue is changed.
A big thank you to everyone in the modding scene, and particularly to Mackinz, whose work inspired me to create this mod.
