Form CSS + Social Icon Hover CSS

Site URL: http://www.differentkennedy.com

Couple of questions regarding some custom CSS tweaks I've been working on: 

• Custom Form: [see attached screenshot]
  • Field background - is it possible there is an overlay applied to SS forms? My background hex is the exact match for grey in the menu and yet it is noticeably darker. I have a couple of overlays on images within css but wanted to see if there was an inherent on in forms before I dug through and messed something up. EDIT: SOLVED
  • Field input border - managed to change the selected field background color to white - but would love to remove the blue border -- border-color: is not working here for me is this possible?
  • Email field input type - I have customized the input text font and color yet it seems to be ignoring the email input field - is there a workaround or is this something that can be addressed with additional css?  
• Social Icons: [see attached screenshot]
  • Adjusted color with css [see attached screenshot] and was wondering if there was a way to adjust the inner icon color on hover: ex in the screenshot the twitter icon is hovered on and is showing my css for having it be white on hover - i would love to be able to change the bird part of this icon to navy

Thanks guys!
