Regex Regular Expression string search. Advice request [closed]

I often find my self searchign a page for two keywords. Chrome can only search for 1 keyword.

I found this free plugin:
“Chrome Regex SearchFind” plugin allows for page searching using Regular Expression.

What would be the syntax to search for two words on a page?

Example 1: I wanto to search for “color” and “blue”

Example 2: I wanto to search for “Color” and “blue”

Example 3: I wanto to search for “bLue” and “CoLor”

(basically not case senstive on string search and they can appear in any order.)

Thank you

This works in Google search only.
