[Idiom] to look different like

[englishhobby]

Is there some kind of idiomatic expression I could use to complete the sentence 'They look different like...'?
I think 'like chalk and cheese' doesn't work in this case because it is used to talk about personalities.

There are two main problems with your question.

1. We don't say "They look different like ..." at all. That's not a natural construction. Nor, for information, is "They are different like ...".
2. If you use "They look like ...", you are talking about appearance. Is that what you're aiming for?

You might be looking for "They look as different as ...". I can't think of a common idiom that fits there. Is there one in Russian?

Yes (I need some idioms for the topic 'Appearance'.)

There is just one, and it's a bit rude, very colloquial: 'they look alike, just like a pig and a hedgehog'. And in Russian it's a rhyme.
But we don't seem to have a neutral idiom either. I started this thread because I noticed my own mistake. I had made a sentence of my own (for a textbook) which sounded like this: 'They look different, like chalk and cheese'. Then I realized that you can't use this idiom to talk about appearances.

That's what I found on the Internet (I doubt they are common in English):
1) They look as different as peas and carrots.
2) They look as different as night and day.
3) They look as different as pumpkins.
4) They look as different as right and wrong.
5) They look as different as a truck and a skateboard.

You're right — they aren't common.
