change color series elements in iam and idw

[Brethil]

Good morning to all,
I have the following problem, why a certain set of elements changes color beyond a certain number of series?
in my case the part that I care about over a certain serial number goes from black to purple; the problem is that in the table the series of pieces remains purple...and should be black..sigh
Any advice?

thanks to all in advance

Maaa... goes from black to purple because there's a rule you imposed?
or for reasons you can't explain?

ninth, originally the piece is black, but if I serialize over 40 components I become all series purple...uff!!! ^
