as discussed in my email:
colour the "max" values in a brighter colour than red, because for red, blue and green
overall colouring, the part of the display where the "max" values are
printed into is somehow dark, red figures are very hard to see there. The
white and green figures on the other parts of the display are much more
easy to view...
I use the app on a Nokia 7 plus - so not a big 6.8" screen, but nevertheless 6" - for me the green and blue design is so dark that the dark red figures cannot be seen, especially by night.
