After successfuly disabling the autofill's yellowish background-color, I stumbled upon another feature.
Each of my input elements have a background image, and every time I focus on a text input, the browser suggests values I used before in a drop down list.
After I pick a value, the autofill covers my entire background and hides the image.
Here's my html and css (elaborated in JSfiddle):
<section class="formContainer">
<img class="sesameLogo" src="~/Content/Images/Site/sesamelogo.png" />
<form id="signUpForm" class="pageForm">
<input type="text" name="decoy" class="decoy"/>
<input type="password" name="decoy" class="decoy" />
<input type="text" placeholder="Full Name" name="FullName" id="fullName" />
<input type="text" placeholder="Email" name="email" id="email" />
<input type="password" placeholder="Password" name="password" id="password" />
<input type="password" placeholder="Confirm Password" name="confirmPassword" id="secPassword" />
<section id="actionBtnsCont">
<button id="btnSignUp" class="mainBtn" type="button">Sign Up</button>
<label class="genContextLbl">or</label>
<button id="btnSignIn" class="genBtn" type="button">Sign In</button>
</section>
</form>
