Need to change color of text on input form on mobile site

I have recently made my website responsive, it is a joomla site, and on the mobile version anywhere that I have a form, when you type in the text you can barely see it because of the color. I have been playing around in the css trying to add color to it but to no avail. Could you please help me crack this thing, it is driving me nuts and several people that have tried using the form have complained about it. The website is http://ift.tt/KDT9s6 and the online giving is an example of where it does this. Thank you a bunch!
