Update to 2.6.1 lost h1, h2, h3 font color…

Hello Kriesi’s team!
I’ve just updated to Enfold 2.6.1 and I’ve lost my heading font color and widget title color…
My (maybe old) css is :

.flex_column h1, .flex_column h2, .flex_column h3, .flex_column h4, .flex_column h5, .flex_column h6 {
font-weight: normal;
color: #a2e619;
}

#footer .widgettitle {
color: #a2e619;
}

After update, font-weight is working but my font color is white…

Any idea?
