Collection Colors

I went searching on this place to see if this has been discussed but the only place I saw it was on dev talk by the user slowk1d and it only had six likes at the time. However. I didn't see it on here. So forgive me if this has already been suggested but slowk1d created a really simple image that would seem easy to integrate for custom colors for collections. Here's what the post said

"With large-scale scenes with lots of objects and collections, being bound to only 8 colors feels limiting sometimes, and being able to assign custom colors to collections would improve a lot the reading in the outliner and speed up differentiating a collection from another."

Don't you all agree? This would be very helpful and useful especially for larger scenes. Is something like this already in the works or no?

Thanks
