Riddle to solve

I invented a riddle, if anyone is up to solve it.
This riddle came into my mind to find a way to represent the possible colors of the tag into a scheme, in order to be able to choose them.


"Represent all the possible combinations of couples of Quake font colors (black excluded) in the minimum space of a table, where each cell corresponds to a color. (Every color should touch each other color, itself as well, horizontally or vertically, diagonally doesn't count)"


To better explain what I mean, this is an example where I represent all the combinations of couples of colors (red-red, red-green, green-blue etc..) in a table, but not in the minimum space.
I used 29 cells in this example (the grey one is to be considered empty space, because there was no need to fill it, since all couples of colors where already represented), it can be done with less.

lol key that a real shitty riddle man!

I go for 5 by 4

It's one of the best riddles ever!

Thanks to this riddle I moved from 3rd to 2nd in the special chart for the most intelligent person ever, just after Tesla.

u use 29 cells.. cuz u just make one grey its not part of the table? ur riddle is a fraud! but if it works like that, fine, 21 cells seems logical then.

5*3 + 2 + 4, the magic calculation   wonder how hard it fails

oh and gj on forum update

You can make less than 21 cells!

cuz u dont count white cells too?

No matter how much I would love to try, I just can't understand fucking anything. I guess my english isn't enough for this...

its not u bro, its key making shit up again

I do not totally exclude that it is actually possible to do with less, since there are some "wasted" cells.
