client.changeThreadColor doesn't work with gradients

[twilight1794]

Description of the problem

The color thread doesn't change when a gradient is specified: (TICKLE_ME_PINK, MALACHITE, RUBY, DARK_TANGERINE and BRIGHT_TURQUOISE). The other colors do work.

Code to reproduce

client.changeThreadColor(ThreadColor.BRIGHT_TURQUOISE, id_of_the_thread)
