I'm using SASS and Compass features to create a custom theme in ExtJS4.
Ive added following parameters in my-theme.scss.

After compass compilation the tab color changes in FireFox but not in IE8.

Please help urgently.
Do I need to change any other attribute also?


Code:
$tab-base-color: #472A49;
$tab-base-color-active: #dee2e4;
See below snapshot in FF:

See below snapshot in IE8:
