After looking over your website, I saw a few things that needed to be changed, so I did. First, I switched the main color to deep blue (#001F3F), which conveys trust and professionalism. It gives off a reliable vibe and has a frequent connection to the legal profession.
To give a touch of elegance and grab attention, I slightly altered the call-to-action button's color to light yellow. That should help you interact with prospective clients, in my opinion.
Since generating leads is your primary goal, I modified the call button to make it more eye-catching and included some keywords that would truly draw in potential clients. I modified the input form as well. It is now more user-friendly and stylish.
