  I think I can see the colour change without any of that when I touch my phone screen, my fingernails look more red when I’m pressing down

    Mine turn white/lighter colored. How hard I'm pressing down is easily visible based on the size of the discoloration.

      Looking again I think if I push with the middle of my finger then it goes redder but if I push at at angle with the edge it goes whiter
