HEX Block
This mod adds a unique building block to the game whose color can be customized to your liking. To change the block's hue, simply right-click on it - a special customization menu will open.
The color is set using an RGB palette, where you can precisely adjust the desired shade by specifying values for red, green, and blue channels. The block also supports a useful option - it can be made impermeable to light by activating the corresponding setting.
