Background color textboxes registration and button

Can someone tell me where i can adjust the color of the background of the textboxes (as in the picture attached).
Also one button color is different in Internet Explorer then in Google Chroome. I did replace the template.php with the new one

We must see your site live to tell you how to fix this. Please give us your link. Also, if the problem is related to a 3rd party component, please ask for help on the component's support forum.

Hey Milo,

Here you can find my live testwebsite and the located issue: themaximumhealthshop.eu/component/virtue...er/edit_cart_bill_to
(It will be updated frequently)
As far as i found out the issue is that the Shopperfields wich can't be removed or edited have a different background then the other Shopperfields. Making them unreadable.

that gray background is defined in:

.joomlaCoreField {
background: #222;
}

in file:

/templates/hot_ecommerce/css/vm_ecommerce.css

for buttons:

.vm-button-correct, .vm-button-correct:hover, .vm-button-correct:visited {
font-size: 12px;
font-weight: 700;
display: inline-block;
text-decoration: none;
color: #777;
}

remove

font-size: 12px;
font-weight: 700;

so it does not resize on hover:
that is in:

components/com_virtuemart/assets/css/vmsite-ltr.css

colors in chrome /ie are same???
