Change Logo on blogpost of certain categories

Hello,

I have a function that will change the logo to a different logo on certain page IDs – now I wanna achieve the same for blog posts of certain categories.

I used the following code:

add_filter('avf_logo','av_change_logo');
function av_change_logo($logo)
{
    if( is_page(ID) ) {
		$logo = "URL_to_logo.png";  
	} elseif ( is_page(anotherID) ) {
		$logo = "URL_to_logo.png";  
	} 

    return $logo;
}

What do I ad?

Thank you!
