I've noticed when checking my site across multiple devices, the colour yellow on the desktop looks orange on another device.
Is there a conversion standard or technique, script or method to convert some colours, or add a filter or any other hack or work around to change the colour across a website depending on device to more closely match particular colours?
you can use the user-agent to detect what device / browser is being used and apply different css or modify through javascript etc. as needed.
heres a link to dynamically load a css file in javascript:

EDIT: This would assume you know which devices / browsers show the colours incorrectly
