I have recently been noticing that despite having a consistent colour scheme configured for all of our magento stores ( Main site/School site), there are major differences in colour appearing in quite important places. The biggest issue is the Add To Cart button, which correctly is green on our school site, but is however grey on our main site. I have looked deep into this issue however cannot get the sites to act in unison.
Secondly the footer (correct as configured via custom css file & magento config on school site) is only correct on our main site until a link has been clicked. For example if you where to go to our homepage via URL you will see the newsletter text in the footer as white; however if you are to click on a link such as "corporatewear" you can see that the text changes to black and the social media icons change to a dark grey as configured in the past.
I have checked the custom css file and there are no lines of code which are isolated to either pages or sites. Any help would be greatly appreciated.
