Carefresh and Kaytee both make natural colored paper bedding!I like Kaytee personally due to it being less dusty,but if you're just mixing it on top it won't matter either way
There are also Carefresh crinkles as a decorative substrate topper,as well as the Eco crinkles!I forget what they're called but they're just brown crinkled paper bedding,mostly useful to top substrate with of course like the Carefresh crinkles but they would look nice in a cage
