Normal colour vision should read number 42.
In protanopia and strong protanomalia the number 2 is read and in mild protanomalia both numerals are read but the number 2 is clearer than the number 4.
In deuteranopia and strong deuteranomalia only the number 4 is read and in mild deuteranomalia the number 4 is clearer than the number 2.
