I'm looking for large balls in standard Lego colors that are detectable by the EV3 color scanner.
So black, white, green, brown, yellow and blue and between 5 and 10 cm.
I'm aware of the Duplo balls:
But they do not seem to exist for all the 7 colors.
Are there any other larger balls from Lego in the standard colors?
Is there any third party offering them?
How much can the colors differ from the Lego colors so that they are still detectable by the EV3 color scanner?
