I get colored tree using tree -C but when I pipe it to less I get results like this:

tree public/ -C | less

enter image description here

How can I have colors in less in this case?

You want the -R switch to less.

From the less man page:

-R or --RAW-CONTROL-CHARS Like -r, but only ANSI "color" escape sequences are output in raw" form. Unlike -r, the screen appearance is maintained correctly in most cases. ANSI "color" escape sequences are sequences of the form:

            ESC [ ... m

So you need

tree -C public/ | less -R
  • The -r switch works for more too. – Ed L Sep 12 '13 at 0:49
  • @EdL I never said it doesn't. – Joseph R. Sep 12 '13 at 1:03

    The question's title asked for "less" or "more", so I thought I'd just note that. – Ed L Sep 12 '13 at 1:04

Passing -r to less will tell it to pass through control characters and escape sequences unmolested.
