Leaves changing colour

Hey lovely people!

I’m just checking in because my violet has been going through some changes and I’m so confused on why lol. I have tried googling and looking up what’s happening but I’m gonna be honest I don’t really know what I’m doing 😅

Can someone tell me why the leaves on my violet are turning this like pinky/orangey/yellowy colour? The leaves don’t physically feel different but the colour change just kinda happened and I’m not sure what I’ve done.

This plant did have a fall a while ago, maybe 6 month now, and I did have to put it in kinda cheap soil at the time but I’ve since repotted it with new soil. There’s constant blooms and it seems overall happy I think? I also have another one that fell too but its leaves look the same as always and it also has constant blooms and seems relatively happy.

Please tell me what I’m missing
