both teams have alike colored kits

My team is FC Barcelona.

FCB's this season home & away kits have dark colors, sometimes it makes confusion to distinguish another team(ex. Liverpool).

If the 1st and 2nd kits have same or alike colors, why don't you use 3rd or 4th kits?

(FCB's 4th kit has yellow color.)

Please consider changing kits

not only FCB, but also other teams that have this problem. Thank you.
