Hermann Tortoise - Shell colour change with new growth

[SkyeFairfax]

Hi all!

I've had Aristotle, a hermann tortoise, for 1.5 years and her new growth on her shell has become a brighter yellow colour than her older growth- please see attached photo. I havent changed anything in regards to her food/habitat. Is this healthy or should i be worried?

Thank you!

She looks fine too me. The lighting makes her look florescent yellow.
@HermanniChris can confirm

That’s right. The lighting pops the color and even so, new growth is often bright yellow or even white.
