Hello,

Although your query is not clear enough on the color you are referring to by “the hint of color”, Assuming that you are referring to the caption text block border color in the Education Hub Pro theme, we can provide you with some Custom CSS to change the color as below :

#main-slider .cycle-caption {
    border-right: 8px solid #f4a024;
}

You can change the “#f4a024” color hex code with the color hex of the color of your choice.

For reference on color hex codes, see the link here : http://www.w3schools.com/colors/colors_picker.asp

If this does not resolve your query and the color section is not the section you are referring to, please explain your query further with screenshot so that we could help you precisely.

Hope this Helps,

Best Regards !!
