Request font colour for in-text citations

I would like to be able to have the option to set all in-text citations to a particular font color such as blue, green and standard black.  Many thesis are full of citations but it’s hard to read and cross check that all the in-text citations in a thesis are also included in the refence list. Recently, I found Endnote had missed some in-text citations, and these were not included in the reference list. This new feature seems pretty straightforward to add. It will be great to see all the in-text ciaitions in a diffrent colour in an essay or thesis and many students would find this new feature a boon!

Being able to define the colour for in-text citations would be very useful, as all the pharmaceutical industry documents I am involved with require in-text citations to be blue - specifically, RGB 0,0,255.
