I have a problem with changing the color of the buttons, from the posts on the main page in the news section.

Even though I changed all the settings to the specified color it needs, which is exactly #e73149, there is still a color #ffbf11 in one place.

I added an entry in the additional css settings : 

.gem-button.gem-button-style-outline {
    color: #e73149;
    border-color: #e73149;

but still the effect is the same and the color of the buttons has not changed

Please help me to solve this simple problem.
