I have made several purple plastic blocks, and when I place these down, they are fine - they look like purple plastic blocks.

Both the One Probe (and helmet), and the WAILA mod, however, report them as being Lime Plastic Blocks when I hover over them, and when I break the purple plastic block, it drops a lime plastic block.

If I then place the Lime plastic blocks, the probe and WAILA say it's a purple plastic block, and breaking it gives me a purple one again.

The same happens with other colours, such as Red <=> Orange or Blue <=> Yellow.
