@Satbeer Singh

oc-content/themes/zara/css/style.css

Find:
#f44336

Replace with:
#33d6ff

And save.

how can i change the words like publish listing and [email protected]

@Satbeer Singh
I recommend to change words via translation (like if you translate theme from English to English).

like...
Publish Listing to Publish Ad Free
[email protected] to [email protected]

please can u do it plzzz its a great request to u...

@Satbeer Singh
Nope, download PO edit and follow osclass documentation on translations.
Or change it manually in theme files (oc-content/themes/zara/footer.php)

@Satbeer Singh

Did you mean changing or edit the following:

Publish Listing text. change into ---> Post free Ad or etc?
[email protected] into ---> [email protected]

Then for the Publish button it is in the inc.search.php

and for the info it's in the footer.php

thank u so much it helped...

now i am suffering from the problem of Favicon which is not getting change...

Try placing the favicon file in root and in --> oc-includes/osclass/gui/favicon

Worked for me.
