XF 1.5 Modifying the functionality of the Rich Text Editor's toolbar?

[GalaxyCitizen]

I'm trying to expand the amount of available colors in the text color palette. Where might I go for this in the ACP? I know on IPS there was a specific area in the admin CP for modifying the toolbar above the rich text editor.

It's not in the ACP. You want to search for /js/redactor/redactor.js. In there, there is an array called colors

Thanks!
