Yellow and white spot on underside of her mandible

[MasterObli]

While I was giving Trinity scritches, I noticed that she had a small yellow spot and a large white spot on the underside of her mandible. I scratched at it with my fingernail just in case it was just part of her beak flaking off but it's not. She didn't care that I was messing with it, her sleeping and eating habits haven't changed, and her poop seems normal. Does anyone know what this is and if it's something I should be concerned about?

Great photo to keep in your files for reference. If you have any near the same to compare with from a couple months ago or longer that would be helpful to see if there are any changes from now going forward. I'm not familiar with the general appearance of beak keratin on her species ( Meyers? ) but a second thought could be beak rubbing on a perch for the whitish part and the yellow color that may have rubbed off from her chewing on a wood toy that is colored yellow. Pay particular attention to what she does in her cage and maybe share what she has in her cage to see what could be the cause. Are there any rough perches in her cage and does she chew on anything else specific?

Unfortunately I don't have any pictures of the underside of her mandible. She is a Meyer's.
Her cage has some rope perches, her food and water dish, and a few toys. If I'm home she's free flight. Little turd keeps trying to nest (she's 19 and just started nesting a couple years ago the little shizz) under the dishwasher so I've had to get creative in blocking it off until I can find a kick plate for it. Rights now I'm using the fitted foam packing things that my GPU was in to block off access to the underside of the dishwasher.

She's always a bit of white near the base of her mandible but it was smaller and the yellow is new. She does like to rub her beak on an orange soft wood toy I got her

I really can't tell if she has scuffed the bottom of her mandible. I would take the orange soft wood toy out for 2-3 weeks and see if that yellow disappears after a few baths. It is possible some of the orange dye on the wood rubbed off onto her beak. If you have any other different colored soft wood toys put those in place of the other. If the bottom changes color to the new wood pieces then that could be the culprit for the color.
