Despite both being coloured the exact same colour, in order for it to achieve it’s true colour, you have to relaunch the server, which is a huge pain in the ass when making pixel art.
Secondly, whatever this thing is i forgot the name of it
Thank you for the report. I’ve been able to replicate the issue with the colourable items and we have figured out the likely cause. I’ll look into it asap.
This is fixed in update 0.6.3.0. This has been happening with other specific items as well, including the haunted cauldron. As an unfortunate side effect, the items with the broken colours need to be stashed and respawned for the colours to be applied properly on the next load.
