Hi Nikolas.
Thanks for your kind words.
I`ve just submitted the changes you suggested. #350,
#351, #352, #353, #354, #355, #356, #357, #358. I put the dot in the middle. They are colored with one of the colors of each logo. If you don't like this option they can be colored in the same gray than the motto. And I submitted a grayscale one, too.
Please, let me know if you have any other suggestion.
Cheers.
Castiza
