Could someone please explain how you would translate differently "the colors black, white, and grey?"
Thank you!

[Ektoraskan]

Siyah, beyaz ve gri renkler.

In one of the previous phrases something was yellow and green, and that was (something) sari ve yesildir, the -dir for 'to be'. Why is there no 'to be' in this sentence?
