Newbie Question on Colors

Hi, I am dropping in to ask a question of you experts. I have a few Christmas cactus that I have had for several years. Two of them have changed color this year. I have never had a peach nor a yellow but this year one of my pale pink is truly peachy orange and my white is extremely yellow. I do have a younger pale pink and a white that are the same as last year as well as my red. I did not repot after last year, nor have I changed where they stay.

Here is the "pink" one that is orange.

Here is the former white one that is now yellow.
