I am using the portable version. None of the custom colors are working: Pick a section, change the color, click accept, nothing happens.

What am I missing?

I tried changing colors on multiple machines, and with the installed version of Tixati, and I get the same behavior: nothing happens.

Windows 11 pro.

It works fine for me.

You have to make sure the color box above the 'use default' check box changes color. that is the color that will be used when you hit the accept button.
