Highlight multiple individual cells in a large workbook linked to a single cell on summary page

I'm working on a large price book database where we have multiple sheets pertaining to various parts of pool building such as excavation, steel, shotcreet, plumbing, etc.  I have a summary sheet where I total up the cost of the various components and this cost is comprised of multiple cells on different sheets within my workbook.

Is there a way I can automatically highlight all linked cells with the same color as the summary sheet cell so that when I go back through the sheets I can confirm I've not missed any data?  Is conditional formatting an option?

I'm fairly versed in excel and this one has me stumped.

Thanks in advance for any help!
