Change colors of svg images

Hello.
I want to change the background and Fill colors of the svg images of the devices : Online - Offline.
I changed the values: mapColorOnline , mapColorOffline in the web/app/Style.js file

I enabled Debug mode: <entry key='web.debug'>true</entry>

But nothing is changed.
is there another place to change?

Have you cleared browser cache?

I restart apache . and it's works.
thank you Antonov for your repsonse
