It works fine, but I didn't like the blue characters of the display (they are black in the photos)

The design beautiful, the brand, the computing features, which I will probably never use in my life, but.
Misleading the consumer. The display is shown with high contrast BLACK numerals. And on a light background. However, the reality is that the numbers are ugly blue and the background is not clear, but you can see the individual points from which the numbers are created. If I lower the contrast, the background sort of disappears, but the digits fade. If I increase the contrast, the numbers will be highlighted. but on a blue background. The result sucks. Visibility from the side is tragic.
Maybe it's a great calculator, but why does it have a worse display than an old calculator from a manufacturer I'm quite unfamiliar with? How much do I have to pay
The photos are first set to low contrast and compared to the old one. Then the tall one is just about legible.
