Applicable Dyes is a server-sided mod for allowing players to directly apply dyes to dyeable blocks.

Shift Dyeing:

Allows players to dye blocks only shifting. If it's turned off in the config file, then shifting restricts you from dyeing blocks instead.

Solid Block Dyeing:

Allows players to dye solid blocks, e.g. Concrete, Terracotta, Glass Blocks & Panes & Glazed Terracotta. This can also be changed in the config file.
