I opened an issue on Kodi's GitHub about colors replaced with white ones after last 2 updates in Arch linux, and someone suggested to post here instead.
But this happened after a Kodi Nexus update so I'm not so sure:

I cannot reproduce this behaviour with Windows.
Unfortunately I can't test with linux.
Switch off Kodi and delete "\userdata\addon_data\skin.titan.mod.beta.matrix\".
And then restart kodi. 
See if you still have the wrong colours.

Install the latest nightly version and you'll see what it looks like when all the colors white.
