Can dojo rooms be colored multiple times?

[DesuTronic]

The polychrome has a message: "Once polychrome is fully funded additional color alterations will no longer be possible."

Does this mean each room can only be colored once? Or does this mean I can still color the parts s of the room that haven't been colored. For example if I color the primary color but not the secondary I can then later do the secondary?

How does it all work and why is it even that the rooms can only be colored once?

it needs time to do the coating so that means you cant do any changes in that time

yes you can recolor the room

Then what does the "Once polychrome is fully funded additional color alterations will no longer be possible."  mean?
