Dirty white rose

At the end of June it is the largest rose in our garden. I don’t know why, but instead of being white, the rose became dirty white. This is not dirt on the petals. This is some kind of mutation of the flower. This is the first time I've seen this while gardening. Nature is very strange this year.

And this is a video of our rural life in summer
