Xxx-gray-750/850/950 values?

Pretty heavy user of Tailwind CSS here, wondering if any of you have found the default palette lacking a little for dark modes?

I've got custom values for gray 750 and 850 as I feel it gets light too quick. The true gray / warm gray colors don't mesh too well with the cool gray from what I've found.

If anyone could share their tailwind.config.js that'd be awesome
