Yes ! I had not thought of template file...
Thank you Michael !

Finally!

After all this time, I broke down and set up a "Default.3dm" template file. :-o

I made up two dozen colors for the materials bank which should come in handy for bouts of creativity.



And... if you want to bring your default colors into any existing model, simply go to Import and choose your "Default.3dm" template file.

Cool tricks!
And for the colors you can name your default .3dm following that you have made and import it! ;
Spring.3dm, summer.3dm, autumn.3dm, winter.3dm...
