Gary Rains

Hi, my name is Gary, I'm hearing, but have always wanted to learn sign language, and I'm my current job, I meet a lot of deaf people, so I've begun to learn. Ive picked up a sign language book, and I'm getting on alright, but I was wondering, is there a sign for or? If I was asking someone for example, what their favourite colour was, I would ask black or white etc. So is there a sign for 'or' or would I list the colours and they folllow it up with the 'which' sign? Thanks in advance, and I look forward to learning sign language 😁
