Make A similar Form

Hi All I have a contact form here: http://www.greenpheasant.co.uk/fill-form/

I am trying to emulate this: https://miloanbroker.com/SecuredLoan/NewQuote

A. I wanted to know how I can
1. Change Text of some of the main headings from black to #398A65
eg. headings such as
1.About the Loan
2.About the Security Property
3.Is the security property: and so on

B.Going back to https://miloanbroker.com/SecuredLoan/NewQuote how is it possible to create fields with highlighted answers to pick e.g. ”Is the security property:”

C.How can we change the colour of the submit and Go buttons on
