In my summer vacations we played Uno® almost everyday

but my father in law struggled with the green and blue cards

and had some trouble to distinguish them...

  

I searched the web when i returned home (28/08) and didn't
find any Uno® version suited for them so i decided to create

my own using Miguel Neiva Design color identification

system: Coloradd®.

After all the work i found out that it was announced on 6/09/17

that Mattel is already making a version with Coloradd®...

I do not own any rights to Uno® or ColorAdd®, this is just

a design exercise, a possible solution to this problem.
