Chang colors of one button on page

Hi,

I’m trying to change the color of a button. I insert the button and change all the colors, but somehow it doesn’t have any effect. It keeps on having the theme colors (green button), although I all set them to “choose my own colors”. The text color will change, but the background color stays green.

I want a white button with red text.

[av_button label='Test button' icon_select='yes' icon='ue800' font='entypo-fontello' link='manually,http://' link_target='' size='small' position='center' label_display='' title_attr='' color_options='color_options_advanced' color='theme-color' custom_bg='#444444' custom_font='#ffffff' btn_color_bg='custom' btn_custom_bg='#ffffff' btn_color_bg_hover='custom' btn_custom_bg_hover='#eaeaea' btn_color_font='custom' btn_custom_font='#ffffff' id='' custom_class='' av_uid='' admin_preview_bg='']

Can you help me set them to the colors I want?
