Changing Feat Text Shortcode Icon Color

Greetings,

I’m trying to change the icon colors on this page: http://hothouseyogi.com/special-confirmation

Here’s an example of the shortcode as I have it:

[feat_text title="Hilltop" icon="location" icon_solid="yes" icon_color="orange" href="https://www.google.com/maps/place/Hot+House+Yoga/@36.8487087,-76.0373994,18z/data=!3m1!4b1!4m2!3m1!1s0x89baea55ccc73751:0xc7fef7087ceb578c" type="2"]1952 Laskin Rd
Virginia Beach, VA 23454
(757) 428-0099[/feat_text]

I’ve tried a number of variations for the icon_color setting, but the icons remain blue. Am I doing something wrong?

Thanks!
