For the left number, the top looks more like a 7 than a 2. But the ‘foot’ is kind of too broad for a 2 yet too narrow for a 7. For the right number, it looks like a 4. I’d say that the green pebbles on a mostly grey and slate background have too much difference in color, so that even a color blind person could see it. I have normal color vision, BTW.
