How to change tab colour of post listing

Hi, sorry if this has already been listed but I have been unable to find it. Could you please advise how to change the colour of the POST LISTING TAB at the top right on header, now orange in colour.
Thank you.

 

It is not possible to change its color because it is a image, If you want to change its color then, Go to images directory present in your theme directory and replace your image with present post button image or edit it.

The name of images is
1. "post-btn-center.png"
2. "post-btn.png"
3. "post-btn-hover.png"

Note:- Use same name for your edited image and remove the current image.

 

Thank you Gourav, appreciate your help.

Best regards
