SUMMARY It seems that currently, the user input is using the text hint colour (normally a dim colour) and the output is using the default text colour. But this, in my opinion, makes it difficult to see the input whilst typing numbers. Wouldn't it make more sense just use the same text colour or the input and maybe use bold font for the output? Also, the operators (+, -, C, etc) are dim. At first I thought they were disabled. I don't know why they are dim. Maybe other people have different opinions what are the best colours, so maybe the best way is just allowing users to customise the colour and font weight of the following texts: 1. Input 2. Output 3.
