How does my tortoise look? (concerns)

[OctopusMagic]

Hi everyone. I took some photos of my tortoise. Overall, I think he looks pretty healthy and he's active and eating and all that. The underside of his shell (the plastron) has some pinkish coloration to it. It's been coming and going for about 9 months or so now with no other signs that I've noticed. I'm thinking maybe it's just from growth as the plastron isn't rock solid yet. Let me know what everyone thinks about this and my tortoise in general. Thanks

He looks good to me. Nice colors and markings too.

He looks good, but a little pale. Does he get natural sunlight?

Thanks Tom, that eases my mind. @WithLisa He hasn't gotten outside in a few months as it has been cold around here. During the summer though he gets a few hours of sun each day for ~4 months if I can help it. Looks like this spring/summer I'll have to ease back on the sunscreen
