Peachy pinky Moses

Some of the leaves near Moses' base seem quite peachy/pinky, rather than the rich dark greens and purples I'd hope to see...

The leaves are also floppy rather than firm, and feel soft to touch (as if they're a bit watery inside?)

I'm not sure what the issue is - I imagine it might be overwatering, but I haven't watered him in quite a while. The soil definitely isn't dry to touch, but also isn't moist. It's just sort of a clump.

Perhaps I have overwatered him. I was worried about sunburn, but maybe the lack of bright light over winter has made Moses a little sad (more sad than the Chinese Money Plants and Spider Plants).

Let's hope he'll perk a bit more in the brighter days to come...
