Hi Dinos,

re:
> Is this how it supposed to be and i should just correct it in the theme editor or is it a bug?

I guess it's a bug but the behavior is the same in v4 for the X/Y/Z axis colors in Options > Grid.

I'll fix it up so that it will take relabeled axis settings into account.

It looks like the axis icon colors (for axis icon in lower left corner) is doing it ok.

Thanks,
- Michael
