I have two combinations commonly used on products that are difficult for me to differentiate. Yellow/green as some switches use to indicate 100meg vs 1gig. And red/orange as on the RB750UP look identical to me.
The mikrotik FTC11 has a pretty unique combination that seems to work well. Its a yellowish green, blue, and a magentaish color. Very easy to distinguish.
