Colour of Social Icons in the header

Hi there, can you advise how i can change the colour of the social icons in the header please, i would like them to stand out more, is it possible to make them slightly larger also?

Thankyou and regards Keith

Hi,

These icons are based on image file, please change this file to modify the color: wp-content/themes/Fest/images/social_icons.png

thankyou, can i also change the size this way?

in relation to the social_icons.png file that you are referring to, if i have several different social media links and images, how will changing one image resolve things. is there not a separate facebook image, twitter etc?

thankyou and regards Ketih

It's one sprite image, so it requires more modifications of css code, please check the example here:
