"Can you see this color?"
Translation:Ти можеш бачити цей колір?
As a native Ukrainian, I would never say it like this. I would rather say "Ти бачиш цей колір?" ("Do/can you see this color?") or "Ти розрізняєш цей колір?" ("Can you distinguish this color?").
I don't know which skill or lesson this from but it might be trying to introduce можеш. Also, can you tell me what the infinitive of можеш is? I forgot :P
