Change form button colour for single page only

I need to change the CTA button background colour on the two forms that appear on this page. I did have some code previously provided for this but I have since jigged the page around following feedback.

The Log in CTA in the header and Subscribe CTA in the footer must stay in their original black colour - so only the CTA's on the two forms are to change (Request a Free Consultation).

The colour is to change to #41986C 

See if this works

#collection-648c4211e872940647bd16de .sqs-block-form .button.sqs-button-element--primary {
  background-color: #41986C !important;

}

Thanks @jaeveedee but this didn't seem to work sorry.

@WR-Mike can you leave the code in there? I'll be able to check it out and see why its not working.

Hi @jaeveedee Sorry for late reply, i've been away. The code had been left in  (and is still there), see attached.

@WR-Mike that needs to go in custom css or you need to be <style> before it and then </style> after it, it can't just be pasted in the page header code injection without html tags. Better to put it in Custom CSS though so it's easier to track down.

Thanks @jaeveedee that has worked. Could you also help with the same on this page below. All future pages I create can be duplicated from the below page so we wouldn't need to do this again.

@WR-Mike do you want every single form block on your site to have that color button? If so you might be able to just remove the #collection part before that .sqs-block-form to make it work on every page. Try that first and if not we can add more selectors to make it more specific.
