create color theme under new folder, come back it is gone. how to save a palette

[mintintegral18]

Hi, I right click under my untitled.xar folder, in the Color Gallery. Select New, New Named color. I create 3 new colors, seen in screen shot. I save project. I close Xara. I reopen Xara. my colors are not saved.

also, is there a CSV file format, perhaps I could import names and color codes, like
my yellow,ffffe1
myblue,0078cc

This would save me a bunch of right clicking.
