Hi Jacob

Thanks for posting in the community! You can change the background fill for equations however it is not currently possible to change the text color. If adding this functionality would be useful for you please let us know via our Product Feedback Space. I apologize for any inconvenience!

I got around this by using Latex's original colouring feature. Let's say you want a coloured logical 'and' (wedge in tex) you can type this in the equation window:

definecolor{mycolour}{rgb}{r g b}color{mycolour}wedge

change the r g b to get your desired colour.
