Visha-

I'm not really sure what yours is doing other than changing the top row colour in each of the sub-process pages.
If I change anything in the main equipment boiler to "boilers" it does not show up in the boilers page.

I am also not sure why there are other sub-processes in each of the sub-process pages. Ideally, I need boilers to look totally red, lighting to be all blue, etc.

Thanks for trying though.
